The specific value of Po377 and Po378 is equal to the value that the encoder line number of servo motor
divide by pulses of external encoder running if motor takes a turn.
3) Set alarm output

If the error turns within Po379 exceed pulses set by Po380, the drive will jump to AL-31 alarm, error will
be removed every turn of Po379.
(2) Wiring Instruction
SD20 series servo drive has 2 group of pulse receiving circuits, one is for receiving the pulses of open
collector type, and the other one is for receiving the pulses of differential type. When using the function
of full closed loop, user should confirm the connections of servo based on PC/PLC and the output form of
related encoder, do not wiring randomly. See below for details:
