9.3.5.2 E1: Input terminal parameter
E1: Input terminal parameter
5 multi-function digital inputs (X1, X2, X3, X4 and X5) are available. Frequency
controller for pump drive used the digital inputs X1(E1.00=30), X2(E1.01=33), X3
(E1.02=31), X4 (E1.03=41) and Frequency controller for cooler used X1(E1.00=35)
digital input.

• 0: Inactive
• 30: Second frequency setting source activation
: For the frequency converter for main pump electric motor, the second frequency
setting source is set to AI2 analog input by setting parameter E0.02.
: When X1 input is active, the actual setting frequency is set by the second
frequency setting source (AI2 analog input).
• 31: Second run command source activation.
: Used for switching to the second run command source. X5 enables remote drive
start.
33: Error signal N.C. contact input.
- If the defined input is open, the external error signal is active and the system
stopped.
- If the defined input is high, there is no external error and the system can run.
This setting is used as fault signal N.C contact input for Max oil temperature, Min oil
level and Max main electric motor temperature.
• 35: Forward running (FWD)
: For the main pump drive, X3 starts the forward running
: For the cooler drive, the signal from the main pump drive to X1 starts the cooler.
• 36: Reverse running (REV)
• 41: PID deactivation via X4.
