Standby Mode decreases how much power the drive consumes when it is in standby.
Standby Mode waits for the drive to stop, then uses the relay output of an MFDO terminal to shut off the input
side electromagnetic contactor (MC) and then shut off the main circuit power supply.
Note:
These conditions are also necessary for Standby Mode:
• Connect an external 24 V power supply.
• Connect a electromagnetic contactor to the drive input side and connect the MFDO terminal set for H2-xx = C [@Standby]. When the
MFDO terminal is OFF, the electromagnetic contactor must be OFF.
• Frequently starting and stopping the drive and regularly opening and closing the electromagnetic contactor will decrease the service life
of the drive.
A - Drive
B - MFDO Terminal
