Notices to Quick Debugging
I. Confirm that wiring is correct.
● R, S, T and U, V,W should not be connected reversely and loosely.
● Check whether the input voltage is three-phase 220V or single-phase 220V.
● Check that Pin 18 in CN1 interface is correctly connected with +24V and that Pins 36 and 9 in CN1
interface are correctly connected with 0V. Poles should not be connected reversely.
● Check that +5V in CN2 interface is correctly connected. Poles should not be connected reversely.
● Check whether the cable for the motor is short circuited or grounded.
● The wiring for the same motor should correspond to the same driver.
II. etermine Energizing Sequence.
● The heavy current and control electricity of
MG
-1000 series of servos are electrified at the same time.
● If the brake of the band-type brake motor is not controlled by the servo, the brake should not be
electrified until the servo is enabled for more than 1 second. Only in this way can the position
precision and safety of the equipment be guaranteed.
● Due to integrated design of the heavy current and control of
MG
-1000 series of servos and adoption of
power-down delay discharge, the internal heavy current is immediately cut off after power supply is
cut off and the delay discharge of display and control circuits automatically cuts off after several
seconds.
For successful use of
MG
-1000 series of drivers, please carefully read the sequence diagram below:
