CN1-4 These devices output pulses of encoder output set in [Pr. PA15] in the
differential line driver type.
CN1-5
In CCW rotation of the servo motor, the encoder B-phase pulse lags the
encoder A-phase pulse by a phase angle of /2.
The relation between rotation direction and phase difference of the A-
CN1-6
phase and B-phase pulses can be changed with [Pr. PC19].
CN1-7
CN1-8 The encoder zero-point signal is output in the differential line driver type.
One pulse is output per servo motor revolution. This turns on when the
CN1-9
zero-point position is reached. (negative logic)
The minimum pulse width is about 400 s. For home position return using
this pulse, set the creep speed to 100 r/min. or less.
CN1-33 The encoder zero-point signal is output in the open-collector type.
CN6-3 This is used to output the data set in [Pr. PC14] to between MO1 and LG in
terms of voltage.
Resolution: 10 bits or equivalent
CN6-2 This signal output the data set in [Pr. PC15] to between MO2 and LG in
terms of voltage.
Resolution: 10 bits or equivalent
Connect
or pin
