The speed controller shown above uses a single-phase 100/115 VAC power supply input.
Switch
Set the switch to “H” if the cable between the motor and speed controller is
less than 10 m (32.8 ft.) in length. Set it to “L” if the cable length exceeds
10 m (32.8 ft.).
This input functions as the Alarm-RESET
input when a speed controller protective
functions is activated.
This input is used to connect the lead wire
of the regeneration unit’s internal thermal
protector.
These are connected for speed control by
the external speed potentiometer or
external DC voltage.
When the protective function is activated,
this output is set to OFF and the motor
stops.
This output is used to monitor the motor
speed. Pulse signals at a rate of 12 pulses
per rotation of the motor output shaft.
