Forced Operation - Omron RX2 Series User Manual

8 Applied Settings
The inverter shuts off the output and, after the contactor release delay time passes, the control signal
039[CON] is turned off. (10)
The operation varies depending on whether the contactor check signal 107[COK] is set to the input ter-
minal function. (11)

Forced Operation

Forced Operation Mode
In this mode, the motor runs at a fixed speed without interrupting the output of the inverter.
Set the [PA-01] forced operation to enabled 01 and turn on the [EMF] emergency forced operation
terminal (input terminal: 105) to enter the forced operation mode.
The command for the forced operation mode is set to [PA-02] the forced operation frequency setting
and [PA-03] the forced operation rotation direction command.
Precautions for Correct Use
• Once the forced operation mode is turned on, the inverter keeps operating until the power is
off.
• When using the forced operation mode, make sure that the system is safe if the operation
continues.
• Enabling the overcurrent retry, overvoltage retry, undervoltage retry or instantaneous power
failure retry requires a separate setting.
• After the [EMF] emergency forced operation terminal (input terminal: 105) is turned on, the
input terminal function except for the following are disabled.

If the 107[COK] is not turned off during the contactor check time, the inverter trips with
the [E110] contactor error.
The inverter still does nothing.
