Test Running
6.1
Precautionary Checks Before Test Running
CAUTION:
After mounting and interconnections are completed, please re-check for:
* Correct connections.
Miswiring of L1 (R), L2 (S), L3 (T) and T1 (U), T2 (V), T3 (W) will destroy output section of unit.
* No short circuit conditions exist on output circuit.
* No loose screw terminals are left behind.
* Correct input power supply is present at primary of line disconnect.
WARNING:
460VAC line power to 230V series inverter will destroy power section of the unit.
CAUTION:
* Only start the motor if motor shaft rotation is completely stopped.
* Even with light loading, never use a motor whose nameplate amperage exceeds the inverter rated
current.
* When starting and stopping the motor, be sure to use the FWD/REV keys or remote control
inputs. Never apply a contactor between the drive and motor or a contactor on the input of the
drive to start and stop the drive.
NOTE: Never start inverter via magnetic contactor on input power supply side.
Never start the motor with an output contactor.
DANGER:
Insure inverter and motor are in safe operating conditions prior to turning on
supply voltage.
5.4.3 Emergency stop via digital operator in remote control mode
Inverter will be stopped via remote switches if it is in remote control (
Fn10=1, Fn46=5
), but in-
verter can also be stopped by pressing "STOP" and "REV" keys simultaneously on the digital opera-
tor in an emergency situation in either case of
Fn10=0
or
Fn10=1
.
