Note
Special features when the essential service mode is either activated or deactivated
Signal p3880 = 1 activates the essential service mode:
• If the motor was switched off by activating essential service mode, the converter switches
the motor on.
• If the motor was switched on by activating essential service mode, the converter switches
the speed setpoint to "ESM setpoint source".
Signal p3880 = 0 deactivates the essential service mode:
• If one of the OFF1, OFF2 or OFF3 commands is active, the converter switches off the
motor.
• If neither OFF1, OFF2 nor OFF3 is active, the converter switches the speed setpoint from
the "ESM setpoint source" to the normal setpoint source.
Note
Emergency operation is not fully functional until one of the following requirements is met:
• p3880 is wired offline; a POWER ON of the CU must then be performed after the
download to the device.
• p3880 is wired online.
