Interface
4 Interface
The standard PositionServo drive contains seven connectors: four quick-connect
terminal blocks, one SCSI connector and one subminiature type “D” connector. These
connectors provide communications from a PLC or host controller, power to the drive,
and feedback from the motor. Prefabricated cable assemblies may be purchased from
Lenze to facilitate wiring the drive, motor and host computer. Contact your Lenze Sales
Representative for assistance.
As this manual makes reference to specific pins on specific connectors, we will use the
convention PX.Y where X is the connector number and Y is the pin number.
4.1 External Connectors
4.1.1 P1 & P7 - Input Power and Output Power Connections
P1 is a 3 or 4-pin quick-connect terminal block used for input (mains) power. P7 is a
6-pin quick-connect terminal block used for output power to the motor. P7 also has a
thermistor (PTC) input for motor over-temperature protection. The tables in this section
identify the connector pin assignments.
DANGER!
Hazard of electrical shock! Circuit potentials are up to 480 VAC above
earth ground. Avoid direct contact with the printed circuit board or with
circuit elements to prevent the risk of serious injury or fatality. Disconnect
incoming power and wait 60 seconds before servicing drive. Capacitors
retain charge after power is removed.
STOP!
DO NOT connect incoming power to the output motor terminals (U, V,
W)! Severe damage to the PositionServo will result.
Check phase wiring (U, V, W) and thermal input (T1, T2) before powering
up drive. If miswired, severe damage to the PositionServo will result.
All conductors must be enclosed in one shield with a jacket around them. The shield on
the drive end of the motor power cable should be terminated to the conductive machine
panel using screen clamps as shown in section 3.2. The other end should be properly
terminated at the motor shield. Feedback cable shields should be terminated in a like
manner. Lenze recommends Lenze cables for both the motor power and feedback.
These are available with appropriate connectors and in various lengths. Contact your
Lenze representative for assistance.
