CHAPTER-4: TEST OPERATION AND ADJUSTMENT
DANGER
Always install the front cover before turning the input power ON. Never remove the cover while
the power is ON. There are sections in the front PCB that are charged with high voltages.
Failure to observe this could lead to electric shocks.
Never touch the switches with wet hands.
Failure to observe this could lead to electric shocks.
Never touch the AC DRIVE’s terminals while the AC DRIVE power is ON even if the operation is
stopped.
Failure to observe this could lead to electric shocks.
Selection of the restart function could lead to unexpected restarting when a fault occurs. The
machine may start suddenly if the power is turned ON, if the run command is present. Do not go
near the machine.
(Design the machine so that physical safety can be ensured even if the machine restarts.)
Failure to do so could lead to injuries.
The machine may not stop according to the set deceleration time when a stop command is issued
if the ramp down to stop function is selected and the voltage / current limit function is activated.
Prepare a separate emergency stop switch in such cases.
Failure to do so could lead to injuries.
Resetting of a fault while the run signal is input could lead to restarting. Always confirm that the
run signal is OFF before resetting the fault.
Failure to do so could lead to injuries.
CAUTION
The heat sink, chokes and dynamic braking resistor are heated to high temperatures, so never
touch them.
Failure to observe this could lead to burns.
Do not block the AC DRIVE’s ventilation holes.
Failure to observe this could lead to fires.
The AC DRIVE operation can easily be set from low speeds to high speeds, so confirm that the
operation is within the tolerable range for the motor or machine before making settings.
Failure to do so could lead to injuries.
Prepare holding brakes when necessary. Holding is not possible with the AC DRIVE’s brake
functions.
Failure to do so could lead to injuries.
Confirm the operation of the motor as a single unit before operating the machine.
Failure to do so could lead to injuries or machine damage due to unforeseen movements.
Always prepare a safety backup device so that the machine is not placed in a hazardous situation
when an error occurs in the AC DRIVE.
Failure to do so could lead to injuries or machine damage or fires.
