Wiring example
5. For wire lead colours, red and black are for power volt-
age. Yellow and black leads are for external variable
signal. The black lead is common for both the power and
the signal. Observe the maximum signal voltage of 5.5VDC.
CAUTION
Observe polarity, otherwise failure or malfunction may
result. Note that rotational direction of the motor does not
change by reversing polarity.
Red: 24VDC (+)
Black: GND (-)
Yellow: 1-5VDC external variable )
Orange: Encoder output (Max output current: 3mA)
6. In order to make ON-OFF operation, install a switch between
the DC power supply and the pump. Installing it between the
DC power supply and the AC power source, the pump may
not run.
7. After wiring work, check that the system is free from the
inductive noise at start-up.
8. Noise accompanies the high-speed switching of the drive
circuit. Check it does not affect peripheral devices.
9. If a power source is shared with inductive loads such as a
solenoid relay, take protective measures against surge.
