・Feeds out a timing signal to activate an electro-magnetic brake of the motor.
・ Turns on the output transistor at a release timing of an electro-magnetic brake.
・You can set up the output timing of this signal with Pr.6A (Mechanical brake
delay at motor standstill) and Pr.6B（Mechanical brake delay at motor in
motion）.

OA+ 11
A-phase output
OA- 12
- Division-processed encoder signal or external scale signal (A/B/Z-phase) is
output in differential mode. (RS422)
- Pr.44 (numerator of output pulse ratio) and Pr.45 (denominator of output pulse
ratio) can be used to set the division ratio.
OB+ 13
B-phase output
OB- 14
- Pr.46 (pulse output logic inversion) can be used to select the logic relation of
phase B with regard to the pulse of phase A, and its output source.
- When using an external scale signal as its output source, Pr.47 (Z-phase of
external scale setup) can be used to set the interval periods of outputs for
phase Z pulse.
Do-1
OZ+ 9
Z-phase output
OZ- 10
- Ground of line drive of the output circuit is connected to signal ground (GND);
not insulated.
- The maximum output frequency is 4 Mpps (after being multiplied by 4).
- Phase Z is output in synchronization with phase A when encoder resolution multiplied by
is in multiples
of 4, but otherwise, the width of phase Z is narrower than that of phase A as it is output based on encoder
resolution, and does not synchronize with phase A.

Note) In the case of 5-wire 2500P/r incremental encoder, the pulse position may be displaced until the first
phase Z is output. When using phase Z as a control signal, use the second signal or others available
thereafter.
