Fault Principle
Contact fault
Fault Cause Solution
Relay problem
The AC drive of high power class uses DC contact. Coil is connected to 24 V
DC power. On normal conditions, the resistance value of the coil is
approximately 3–4 . When the main contact closes, the resistance value at
the two ends of the contactor is below 0.1 . Check the resistance value of
the coil and the closing condition of the main contact when performing
maintanance on site.
Drive board problem
If the fault persists after you perform the preceding operations, contact the
IMM manufacturer.

Fault Principle
Current detection fault
Fault Cause Solution
Hall problem
Check whether hall wiring becomes loose. If not, replace the hall
component.
Drive board problem
If the fault persists after the hall problem is solved, contact the IMM
manufacturer.

Fault Principle
Output short-circuit
Fault Cause Solution
Drive board
short-circuit to ground
Measure whether U, V, W cables of the servo drive are in contact with the
earthing cable by using the diode function of the multimeter. On normal
conditions, they are disconnected. If short-circuit occurs, contact Inovance
