Page 9: Configuring Speeds / Frequencies
CONFIGURING SPEEDS / FREQUENCIES Speed / frequency values are stored as whole numbers (example is 15.25 Hz = 1525). Use the chart below to configure the speeds / frequencies for the configured speed control method. If operating at frequencies below or at 5hz for an extended amount of time an external motor cooling device may be required to prevent motor overheating. -
Page 10: Multi-Step Speed Command
MULTI-STEP SPEED COMMAND Multi-Step speed command can be configured up to 16 speeds. Only use multi-step speed command when speed control greater than 3-steps is required. In the multi-step speed command, 4 inputs as a binary combination of 0 (OFF) and 1 (ON) will determine the command frequency, reference the chart below for configuring the steps and speeds. -
Page 11: Acceleration / Deceleration Times
ACCELERATION / DECELERATION TIMES When adjusting the deceleration times be sure to check the hook block limit for over travel. If over travel occurs either lower the deceleration time or adjust the limit zones. Changing the acceleration time to a shorter time can cause a E01 over-current or E05 over-load fault /trip, if this occurs due to a short acceleration time increase the acceleration time and test again. -
Page 12: Micro-Speed Function
MICRO-SPEED FUNCTION Micro-speed is designed to temporarily restrict the speed of the hoist to a lower speed and to prevent high speed operations until the function is released. The micro-speed function can be configured two ways. 2-STEP MAINTAINED MODE – This mode will switch to a 2-Step maintained speed set. This is helpful where the micro-speeds need to be specific. -
Page 13: Auto-Speed 90Hz Function
AUTO-SPEED 90HZ FUNCTION The auto-speed function will allow the VFD to increase the high speed to 90Hz when there is an empty hook or a light load. You can set this function for automatic or for input activation. The auto-speed function is not available when using 0-10V/4-20mA speed control methods, when micro-speed is active, and or when in tandem mode. -
Page 14: 125% Field Load Testing / Over-Weight Bypass

Page 20: Motor Brake Parameters
MOTOR BRAKE PARAMETERS While operating in closed loop vector mode (AA121 = 10) the motor brake release and set frequencies are controlled automatically and typically do not require adjustment. When operating in open loop mode (AA121 = 1 thru 9) the motor brake release and set frequencies are controlled by parameters that can be adjusted but typically do not require adjustment. -
Page 21: Encoder-Based Operational Hook Block Limits (Clv)
ENCODER-BASED OPERATIONAL HOOK BLOCK LIMITS (CLV) The VFD has the capability to utilize the motor encoder to create digital upper and lower operational hook block limits. This is done with the use of the encoder from the motor while operating in closed loop vector control only (AA121 = 10) and with the encoder- based limits enabled (UE-33 = 1 or 2). -
Page 22: Setting Encoder-Based Limits (Clv)
SETTING ENCODER-BASED LIMITS (CLV) Use the step chart below to set the encoder-based limits. If using switches from the factory use the image below of the blue terminal knife disconnect as reference.

In most applications the encoder will terminate at the main body digital input terminals and the parameters with Main Body will apply. In some special cases an external feedback card will be installed and the parameters with P1-FB will apply. In the case of the P1-FB card CA-90 will need to = 00: disabled. -
Page 25: Load Float (Clv)
LOAD FLOAT (CLV) Load float is term used in closed loop vector control where the VFD can hold a load at 0hz / 0 speed without the use of the motor brake. This function is available when operating in closed loop mode (AA121 = 10) and will greatly increase the life of the motor brake by only using it as a holding/parking brake and not a dynamic brake in normal operation. -
Page 26: Motor Brake Slip Detection (Clv)
MOTOR BRAKE SLIP DETECTION (CLV) Motor brake slip detection is safety check feature that checks to make sure the motor brake can hold the suspended load at the end of each lift cycle prior to removing complete power from the motor. This is safety check feature is only available when operating in closed loop vector control only (AA121 = 10). -
Page 27: Tandem Hoist Ezcom (Speed / Command / Status Syncing)
TANDEM HOIST EZCOM (SPEED / COMMAND / STATUS SYNCING) Tandem hoist EZCOM can be used when 2 hoists are used in tandem operation and require the frequency, hook limit status, command status, and fault status to sync between each hoist. The VFD’s will need to be configured to communicate between each other and the internal logic activated. -
Page 28: Ezcom Setup Guide
EZCOM SETUP GUIDE Step Instruction Configure the VFD’s parameters using the EZCOM parameter chart.

Page 30: Hook Block Syncing / Pulse Train Position Command (Clv)
HOW IT WORKS – The VFD’s use the SN/SP RS485 terminals to send frequency reference, drive status, and command status Modbus registers values between each other. The VFD’s also required the external encoder feedback card (P1-FB) connected. The main hoist will send a 1:1 pulse train from the encoder card to the pulse train input on the follower encoder card. -

Page 33: Auto-Tuning
AUTO-TUNING Field auto-tuning is generally not required. The VFD will be configured from the factory for the connected motor. If field auto-tuning is required, please use the step chart below. NOTE – The E-stop / maximum upper limit will retain function to prevent over-travel into the frame. The VFD will automatically control the AL relay output for brake release command during auto-tuning. -
Page 34: Speed Deviation (Clv)

Speed deviation is the difference between [dA-12] Output frequency monitor and [dA-08] detected frequency monitor. -
Page 35: Dynamic Braking
DYNAMIC BRAKING The dynamic braking is used to electronically brake the motor during deceleration. Dynamic braking required the use of a braking resistor or a regenerative converter. The parameters below only apply when using a resistor. Load-Brake – The internal load-brake absorbs 99% of the dynamic braking. The dynamic braking usage ratio should be set to 3% to detect when the load-brake becomes worn, and maintenance is required. -
Page 36: Over-Speed (Clv)
OVER-SPEED (CLV) The over-speed error detection function judges that the speed is excessive if the feedback speed exceeds the over-speed level. Whether the speed is excessive is determined according to the feedback frequency displayed on [dA-08] Detected frequency monitor. When the speed has exceeded [bb-80] Over-speed error detection level and [bb-81] Over-speed error detection time has elapsed, it is judged as an over-speed error. -
Page 37: Input Phase Loss Protection
INPUT PHASE LOSS PROTECTION When [bb-65] input phase loss selection is set to 01, when a missing phase is detected in input line, the inverter turns OFF its output. This protection function is used to prevent system failure due to unstable motor operation when a phase loss occurs by breakage of the input power cable. -
