8-1 Operation Procedures
DANGER
1. Do Not remove wires when the internal indicator of the drive remains ON.
2.
After power off (30HP below models must wait at least 5 minutes;
40HP~75HP models must wait at least 10 minutes; 100HP above models
must wait at least 20 minutes), Do Not perform any unwiring actions before
drive indicator light (CHARGE) turns off. Use a multimeter with the DC
voltage stage to measure the cross voltage between P(+) and N(-) ports (DC
bus voltage must be less than 25V).
CAUTION
1. Check if the shield of wire is broken after wiring is completed to avoid electric
leakage or short circuit.
2. Screws on the terminal must be fastened.
A. Verify and check the compatibility between power source, voltage, motor, and
drive.
B. Connect the power to drive R/L1, S/L2, T/L3 (three-phases) or R/L1, S/L2
terminals (single-phase).
C. Set all required parameters and functions after power is ON and measure the
output voltage of the drive at U/T1, V/T2, W/T3 terminals to verify if the output
voltage and current are valid. Press
OFF
RESET
when completing all verifications.
D. Switch off the power and wait for
drive’s power indicators off, and then connect
drive’s U/T1, V/T2, W/T3 terminals to the motor.
E. Operate the motor with the drive by low speed after power ON to verify the validity
of the motor rotation direction and then to slowly increase the motor speed.
F. Motor start or stop must be controlled by drive control signal instead of switching
the power ON / OFF. The lifetime of the drive will be significantly reduced if the
invalid operation using the switch control of the power is applied to motor control.
G. Because the starting current of motor is 6~8 times of rated current, Do NOT install
the magnetic contactor between the drive and motor for the motor operation.
H. When using the single-phase power source to drive the three-phase drive (not the
standard type of single-phase power input), first confirm the horsepower of motor,
and then calculate the motor rated current by multiplying the motor rated current
by 2 times to the base value of drive rated current. The drive selection for this
single-phase power must have the rated current equal to the calculated drive
rated value.
Formula: Motor rated current × 2 = Drive rated output current
