Installation & Operation 2-11MN1800
LMPY Series Polynoid Linear Motor Holding Option
Mounting: The rectifier package is wired externally in the stator circuit.
For 115/60Hz, rectifier package CO0126A00 is provided.
For 230/60Hz, rectifier package CO0125A00 is provided.
Rated holding force is only achieved when the keeper plate is against the holding coil. To
reduce shock loads, a shock absorbing connection between the polynoid rod and the load
is recommended.
Switching: Two switching modes can be used for various applications.
Single Holding:
 Energized constantly except momentary interruption to release holding so rod
can be reversed.
 Energized only during period when holding is required.
 Energized only when rod is moving towards the holding end of the stator and
during the holding period.
Double Holding:
 Energized constantly except momentary interruption to release holding so rod
can be reversed.
 Energized only during period when holding is required.
 Double holding coils may be switched together or one at a time.
Note: Double holding coil units are normally supplied with 2 yellow leads and one
small diameter black lead so that the holding coils may be operated
independently by applying rated voltage to the yellow and black lead. The wire
marker on one yellow lead indicates the lead that operates the holding coil on
the lead egress end of the stator. If desired, the 2 yellow leads can be tied
together for simultaneous operation of both holding coils.
