check the voltage value with multimeter ( between +AT and -AT).
2)

- Check input signal (Enable-reference)
3)
When the drive is enabled the green OK LED goes off and the red O.C. LED comes on.
-
Short circuit between motor terminals or motor winding is connected to ground. Switch off and measure
with tester.
4)
During motor deceleration phase the green OK LED blinks.
-You've exceeded max. allowed voltage. Verify filter capacitance value. (See Power Supply chapter).
5)
During operation the motor stops and the S.T. LED comes on.
-Environmental temp. is to high (more than 40°C). Ventilation missing (where required).
6)
Motor goes out of control when enabled.
Encoder signals incorrectly connected (CHA and CHB
