Output signal is open-collector output, so an external power supply
(Vcc) is required. Use a power supply of no more than 26.4 VDC
and connect a limit resistor (R) so that the output current does not
exceed 10 mA. When using neither the speed output function nor the
alarm output function, this connection is not required.
Speed monitor output: Pulse signals are output at a rate at
12 pulses per rotation of the motor output
shaft. (When the pulse duty is 50%)
(Note that this is monitoring of the speed
command issued from the speed controller to
the motor, not that of the speed measured at
the motor's output shaft.)

Alarm output: This signal is output when a protection function for
overload, circuit overheat, overvoltage,
undervoltage, overcurrent or EEPROM error has been
activated. When an alarm signal is output, this output
is turned to OFF between the ALM output and O-COM
terminals.
