PROFIBUS DP Interface

An optional PROFIBUS DP communication module (E94ZAPFB1) is available for the PositionServo drive.
Installed in Option Bay 1 as P24, the PROFIBUS DP module is optically isolated from the rest of the drive’s
circuitry. The PROFIBUS module is a female DB-9 connector. Refer to the PS PROFIBUS Communications
Reference Guide (P94PFB01) for detailed information.

Motor Selection

The PositionServo drive is compatible with many 3-phase AC synchronous servo motors. MotionView
OnBoard is equipped with a motor database that contains hundreds of motors for use with the PositionServo
drive. If the desired motor is in the database, no data is needed to set it up. Just select the motor and click
“OK”. However, if the motor is not in the database, it can still be used, but some electrical and mechanical
data must be provided to create a custom motor profile. The auto-phasing feature of the PositionServo drive
allows the user to correctly determine the relationship between phase voltage and hall sensor signals or
resolver offset, eliminating the need to determine feedback orientation by other means.

4.5.1

Motor Connection

Motor phase U, V, W (or R, S, T) are connected to terminal P7. It is very important that motor cable shield is
connected to Earth ground terminal (PE) or the drive’s case. The motor’s encoder/resolver feedback cable
must be connected to terminal P4.

4.5.2

Motor Over-Temperature Protection

NOTE
The PositionServo does not provide motor over-temperature protection. The user may
connect a KTY motor thermal sensor to the drive as detailed in section 4.1.1 and this
paragraph, 4.5.2, if necessary to satisfy NEC requirements.

If using a motor equipped with an encoder and PTC thermal sensor, the encoder feedback cable will have
flying leads exiting the P4 connector to be wired to the P7.1 (T1) and P7.2 (T2) terminals. If using a motor
equipped with a Resolver and a PTC sensor, the thermal feedback is passed directly to the drive via the
resolver 9-pin D shell connector.

Use parameter “Motor PTC cut-off resistance” (section 5.3.10) to set the resistance that corresponds to
maximum motor allowed temperature. The parameter “Motor temperature sensor” must also be set to
ENABLE. If the motor doesn’t have a PTC sensor, set this parameter to DISABLE. This input will also work
with N.C. thermal switches which have only two states; Open or Closed. In this case “Motor PTC cut-off
resistance” parameter can be set to the default value.
