Interface

The standard PositionServo drive is equipped with seven connectors including: four quick-connect terminal
blocks, one SCSI connector, one subminiature type "D" connector and one ethernet RJ45 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, the convention PX.Y is used, where
X is the connector number and Y is the pin number.

External Connectors

4.1.1 P1 & P7 - Input Power and Output Power Connections
Located on the top of the drive, P1 is a 3 or 4-pin quick-connect terminal block used for input (mains) power.
Located on the bottom of the drive, 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 (refer to paragraph 4.5.2).
The P1 and P7 connector pin assignments are listed in the tables herein.

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.
