5 PositionServo Connections
The standard PositionServo drive contains seven connectors: four quick-connect
terminal blocks, one SCSI connector and one subminiature type “D” connectors.
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.
5.1 External Connectors
5.1.1 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 below
identify 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 miss wired severe damage to the PositionServo
will result.
All conductors must be enclosed in one shield and 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 4.2. 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.
