G
motor wire is not properly connected.
z
Reset input can be used Motor free signal input. As shown in Fig.8, the drive alarm is reset at the
negative falling edge of reset output of controller and the drive cuts off motor power in the low
state(input photodiode of reset input of drive is turn on state)of reset output of controller.
7. Connection and Wiring
7. 1 motor, input signal, out signal, Power connections
DANGER
z
All connections should be made with any power sources turn off and disconnected from the drive.
Electric shock may occur.
z
Only qualified service and installation personnel should install this device.
z
The cable should not have excessive force applied to it and should not be bent beyond a 2.5cm
radius of curvature during normal operation.
z
Choose twisted pair wire for pulse input, reset input, and fault out and the length of these wires
should be shorter than 1 m.
z
Shield these wires ensure that the shield is taken to a low impedance earth ground.
z
Specially, when current resolution of drive is set high and mid or high speed is required, more
attention is crucially required to wiring pulse input signal.
z
Choose motor and power connection wire sufficiently thick.
z
Do not bundle the control wire and communication cable with the main circuit or power line.
z
Keep the control wire and the communication cable at least 100 mm away from the main circuit or
power line: otherwise, noise or malfunctions will occur.
z
Failure to engage the connectors properly could result in faulty connection, leading to erroneous
inputs and outputs.
z
Engage the drive unit connector and peripheral device connector securely with the connectors on
the drive.
z
Shield the motor cable and ensure that the shield is taken to a low impedance earth ground.
z
Earth the motor casing to a low impedance earth ground.
z
Mount equipment that is sensitive to EMI as far as possible from the drive and motor.
