8-1. Speed out
If synchronizes with motor operation that it creates 30 pulses signal
per 1 rotation of motor output axis. Measure speed out frequency to
calculate motor rotation speed.

Example of output circuit connection
·
Signal output is open collector output.
·
Use power of less than DC26.4V to connect restricted resistance
with less than 10㎃.

7. Operation
Rotation direction is when you look at it from output axis of motor.
CW is clockwise and CCW is counterclockwise.
7-2. Controller of transister output type
Use small size connection TYPE relay to open and close DC 12V, 5mA
CW(clockwise)operation :
If it is set at CW and on, then the motor rotates clockwise, If CW
input is off, then the motor stops.
CCW(counterclockwise)operation :
If it is set at CCW and on, then the motor rotates counterclockwise.
If CCW input is off, then the motor stops.
If CW and CCW are put in at the same time and on, then the motor
stops instantly. At then moment, instant reverse operation is not
possible.
Give more than 20msec of time interval between CW signal and
CCW signal inputs.
Do not use SSR(Solid State Relay) on power ON/OFF Motor control
unit may break.
If you are using controller with clamp cliode installed, be careful of power
on/off order.
- POWER ON : Controller ON → Control unit ON
- POWER OFF : Control unit OFF → Controller OFF
When you connect like the diagram above, if you turn the control unit power
on first or if you turn the controller off while control unit is on, then the
electricity flows and motor rotates.
There is a chance that motor might rotate due to power capacity difference
even if you turn the power on and off at the same time.Controller should be
turned on first and control unit is off first in case of power.

7-1. When only operating with the main part
If you turn RUN/STANDY-BY SWITCH to RUN, then the motor rotates.
If you turn RUN/STANDY-BY SWITCH to STAND-BY,then the motor stop.
The rotation direction is determined by the short bar connection status
on the back of the control unit. connect accessory short bar between
CW-COM and CCW-COM. Do not use short bar for other purposes.
