4.8.3.1 Position pulse signal input
The SV200 DC series servo has two high speed pulse intputs, STEP/DIR and PULSH/SIGNH. STEP/DIR supports 5-24VDC, up to
500KHz open collector input signal or differential input signal through the line driver. PULSH/SIGNH supports 5VDC, up to 2MHz with
differential line driver input.
NOTE: STEP/DIR and PULSH/SIGNH CANNOT be used at the same time.

D. Pulse Input Description
●
STEP/DIR Pulse Input
When both STEP and DIR input signals are ON, the motor will rotate in one direction.
When STEP input signal is ON, and DIR input signal is OFF, the motor will rotate in the opposite direction.
The direction signal (DIR) can be configured via SVX Servo Suite software.
The following graph represents motor rotatation in CW direction when DIR input is ON.
