terminals. Never connect three-phase power supply to output terminals U/T1, V/T2 and
W/T3. Failure to comply may result in equipment damage.
Install braking resistors at terminals and B2 only. Failure to comply may result in
equipment damage.
Install DC reactor at terminals and , and remove the jumper connected at
and . Never connect this jumper and DC reactor to any other terminals. Failure to
comply may result in short circuit and equipment damage.
Wiring screws and bolts for main circuit terminals must be screwed tightly. Failure to
comply may result in equipment damage.
AC 220V signal is prohibited from connecting to other terminals than control terminals
RA, RB and RC. Failure to comply may result in equipment damage.
ATTENTION
Since all adjustable frequency AC drives from GTAKE have been subjected to hi-pot
test before delivery, users are prohibited from implementing such a test on this
equipment. Failure to comply may result in equipment damage.
Signal wires should be away from main power lines to the best of the possibility. If this
cannot be ensured, vertical cross-arrangement shall be implemented, otherwise
interference noise to control signal may occur.
If motor cables are longer than 100m, it is recommended output AC reactor be used.
Failure to comply may result in faults.
The coder must be provided with shielded cables whose shielded layer must be well
grounded.
1.1.4 Run
WARNING
Drives which have been stored for more than 2 years should be used with voltage
regulator to gradually boost the voltage when applying power to the drives. Failure to
comply may result in equipment damage.
Be sure to implement the wiring as per Section 3.4 before applying power to the drive.
Failure to comply may result in equipment damage and/or electric shock hazard.
Be sure to confirm the completion and correctness of the drive wiring and close the
cover before applying power to the drive. Do not open the cover after applying power.
Failure to comply may result in electric shock hazard.
After applying the power, never touch the drive and peripheral circuits no matter what
state the drive is under, otherwise there will be electric shock hazard.
Prior to running the drive, make sure there is no person in surrounding area who can
reach the motor so as to prevent personal injury.
