Note 1. Encoder pulse unit.
2. 8 V is outputted at the maximum torque.
However, when [Pr. PA11] [Pr. PA12] are
set to limit torque, 8 V is outputted at the
torque highly limited.
3. For 400 V class servo amplifier, the bus
voltage becomes +8 V/800 V.
PC15 Analog monitor 2 output
Used to selection the signal provided to the analog
monitor 2 (MO2) output.

PC16 Electromagnetic brake sequence output
Used to set the delay time (Tb) between electronic
brake interlock (MBR) and the base drive circuit is
shut-off.
