Make sure "2.8 V ≤ (H level) - (L level) ≤ 3.7 V". Otherwise, input pulses of the servo drive are
unstable, which will cause:
•
When the reference pulse is input, pulse loss occurs.
•
When the reference direction is input, the direction will reverse.
b) OC mode
When the internal 24 V power supply of the servo drive is used:
