Mitsubishi Electric FR-CS82S, FR-CS84 - Frequency Inverter Quick Start Guide

Further information

There is a risk to the life and health of the user if appropriate precautionary measures are not taken. The precautions can be found in the instruction manual of the frequency inverter FR-CS80.

If you have any questions about the installation, programming and operation of the frequency inverter, please do not hesitate to contact your sales office or one of your sales partners. You can reach our technical support at the following number: +49 (0) 2102 103 7914

Control circuit terminal

Wiring method

Power supply connection

1. Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with neighboring wires. If the length is too short, wires might come off.
   Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it
   
   
2. Crimp the blade terminal.
   Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is inappropriate, or the face is damaged.Blade terminals commercially available (as of February 2017)

Wiring of the control circuit

Recommended cable gauge: 0.3 to 0.75 mm²

Input signals

Use a wire end ferrule and a cable for the connection to the terminals where the end is striped appropriately. Single-core cables can be connected directly to the terminals after removing the insulation.

Terminal	Description
STF	Forward rotation start signal
STR	Reverse rotation start signal
RH, RM, RL	Multi-speed selection
SD	Common terminal for the contact input terminal (sink logic). Common terminal (0 V) for the 24 V DC power supply (terminal PC).
PC	24 V DC output and common terminal for control circuit inputs in source logic
Terminal	Type	Description
10	Frequency setting power supply	Used as the power supply for an external device such as a frequency setting potentiometer or digital panel meter.
2	Frequency setting (voltage)	Inputting 0 to 5 V DC (or 0 to 10 V DC) provides the maximum output frequency at 5 V (or 10 V) and makes input and output proportional.
4	Frequency setting (current)	Inputting 4 to 20 mA DC Current input Voltage (or 0 to 5 V, 0 to 10 V) (initial status) input provides the maximum output frequency at 20 mA and makes input and output proportional. This input signal is valid only when the AU signal is ON (terminal 2 input is invalid).
5	Frequency setting and analog outputs common	Terminal 5 represents the reference point (0 V) for all analog setpoint values and for the analog output signal AM (voltage). The terminal is isolated from the reference potential of the digital circuit (SD).
10	PTC input (PTC sensor)	Terminals 10 and 2 serve as an input for a PTC sensor (thermal motor protection).
2
A, B, C	Relay output	A changeover contact output that indicates that an inverter's protective function has been activated and the outputs are stopped.
RS-485	PU interface	The PU connector supports the RS-485 communication.

Components of the operation panel

Appearance	Name	Description
	STOP/ RESET key	Stops the operation commands. Used to reset the inverter when the protective function is activated.
	UP/DOWN key	Used to change the setting of frequency or parameter, etc. The following operations are also enabled:
	MODE key	Switches the monitor screen (item) in the monitor mode. Every key on the operation panel becomes inoperable (locks) by holding this key for 2 seconds. The key lock function is disabled when Pr.161 = "0 (initial value)". Holding this key for one second displays the initial screen. (During normal inverter operation it will appear as the first screen in the monitor mode; during abnormal operation it will appear as the first screen in the fault history mode. Reverts to the previous screen if pressed during frequency setting when the easy setting function is enabled.
	SET key	Confirms each selection. Pressing this key in a mode other than the parameter setting mode will display parameter settings.
	RUN key	Used to give the start command to the inverter. The rotation direction depends on the Pr.40 setting.

Basic operation

Changing the parameter setting value

Change the setting of Pr.1 Maximum frequency.

Operating procedure

1. Turning ON the power of the inverter
   The operation panel is in the monitor mode.
2. Selecting the parameter setting mode
   Press to choose the parameter setting mode.
3. Selecting the parameter
   Press or to show
   (Pr.1). Press to read the present set value.
   (initial value) appears.
4. Changing the setting value
   Press or change the set value to . Press to enter the setting and
   are displayed alternately.

• Press or to read another parameter.
• Press to show the setting again.
• Press twice to show the next parameter.
• Press for one second to return the display to the first screen in the monitor mode (the monitor item initially set in the first screen is the frequency).

NOTE

Error indication	Description
	Parameter write error
	Write error during operation
	Calibration error
	Mode designation error

Basic parameters

¹The factory setting depends on the performance class of the frequency inverter.

Overview of the error messages

If a protective function has been activated, eliminate the cause of the error and then reset the frequency inverter. It is imperative that you follow the procedure in the instruction manual for the FR-CS80 frequency inverter. You can reset the frequency inverter by pressing the STOP/RESET button on the operation panel (only after a serious error), by switching the power supply off and on again, or by switching the RES signal.
