Note
The ground connection from the filter must be wired to solid earth
ground, not machine ground.
If the end-user is using a CE-approved motor, the AC filter combined with the
recommended motor and encoder cables, is all that is necessary to meet the EMC
directives listed herein. The end user must use the compatible filter to comply with CE
specifications. The OEM may choose to provide alternative filtering that encompasses
the PositionServo 940 drive and other electronics within the same panel. The OEM
has this liberty because CE requirements are for the total system.
4.4 Heat sinking
The PositionServo 940 drive contains sufficient heat sinking within the specified
ambient operating temperature in their basic configuration. There is no need for
additional heat sinking. However, you must ensure that there is sufficient clearance for
proper air circulation. As a minimum, you must allow an air gap of 25 mm above and
below the drive.
4.5 Line (Mains) fusing
External line fuses must be installed on all PositionServo drives. Connect the external
line fuse in series with the AC line voltage input. Use fast-acting fuses rated for 250
VAC or 600 VAC (depending on model), and approximately 200% of the maximum
RMS phase current.
5 PositionServo 940 Connections
The standard PositionServo 940 drive contains seven connectors: four quick-connect
terminal blocks, one SCSI connector and two 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.
