GSK DA98A - Connection

DA98A AC Servo Drive Unit User Manual
Connection
● Only qualified personnel can do or check the connection.
● Connection and checking can only be done in 5 minutes after the power supply is
cut off.
● The AC servo drive unit and servo motor must be well grounded.
● Explosion or operation incident may be caused by false voltage or polarity of power
supply.
● Connection can be done only after AC servo drive unit and servo motor are well
installed.
● Ensure the wires insulation and not squeezing them to avoid electric shock.
Warning
● Correctness and fastness of connection must be ensured, otherwise the servo motor
will run in a false direction or the equipment may be damaged by loosen contact.
● U, V, W terminals must not be connected reversely and connected with AC power
supply.
● Servo motor should be directly connected with AC servo drive unit without
connecting capacitance, inductance or filter.
● Prevent conductive fastener and wire odds and ends from entering into the drive
unit.
● Wires and non-thermal protective objects are not permitted to approach to the drive
unit radiator and servo motor.
● Freewheeling diode in parallel with DC relay of output signal must not be connected
reversely.
Caution
Debugging
● Assembly and stable fixation of servo drive unit and servo motor, correctness of
power voltage and connection must be ensured before the power-on.
● Servo motor should make a run in dry run mode while debugging. Loading
debugging can be done after the parameters are correctly set to avoid the damage of
machine and equipment caused by maloperation.
Caution
Usage
● Emergency circuit should be connected to ensure the machine stop and power cut
off immediately when an incident occurs.
● The running signal must be off before resetting an alarm or it sudden restart may
occur.
● The drive unit must be used with the suited servo motor.
● Do not frequently switch on/off the power supply of the drive unit to avoid damaging
the unit system.
● Do not touch the drive unit radiator and the motor in running or the duration after
power-off to avoid scalding by the heat generated in running.
● Don’t refit the drive unit.
