phase) in differential. (equivalent to RS422)
• You can set up the division ratio with Pr44 (Numerator of pulse output
OA –
division) and Pr45 (Denominator of pulse output division)
• You can select the logic relation between A-phase and B-phase, and the
output source with Pr46 (Reversal of pulse output logic).
OB +
• When the external scale is made as an output source, you can set up the
interval of Z-phase pulse output with Pr47 (Setup of external scale Z-phase).

• Ground for line driver of output circuit is connected to signal ground (GND)
and is not insulated.
• Max. output frequency is 4Mpps (after quadrupled)

• The emitter side of the transistor of the output circuit is connected to the
signal ground (GND) and is not insulated.
