MMC Smart Drive Hardware Manual - 230V 1/3 PHASE MMC SMART DRIVE
6. The process is repeated starting with step 1 above as required
If during step 3 above, the user-supplied external circuitry removes 24Vdc from the
"EN" input (usually due to a safety violation on the equipment being controlled), the
drive will fault, and the motor will coast to a stop. The drive must be powered off and
back on to remove the fault condition.
5.2.1.1.2 "EN" operation on non-Safe-off Drives
If the Drive does not include the Safe-off feature, regardless of the sequence of
operation, if the "EN" ever loses 24Vdc, the drive faults, and the motor coasts to a
stop. The drive must be powered off and back on to remove the fault condition.
5.2.2 Power Connector
The Power Connector consists of a non-pluggable 9-pin screw-terminal block, and
provides connection to the incoming AC power and the motor that is being controlled
by the Drive.
