Example 1 Example 2 Example 3
These examples show typical applications. In these examples the encoder Z or Marker pulse is used to indicate the zero
position. An external switch may be used as the Marker pulse to indicate the zero position.
Example 1
This is a direct drive system where the encoder, motor and spindle shafts are directly coupled. This system can use the
encoder for positioning and closed loop vector operation to provide the best performance.
Example 2
This is an indirect drive system where the motor to spindle shaft connection may change. This method also provides for
gearing. The encoder is coupled to the spindle shaft to eliminate possible positioning errors. This method must use open
loop vector speed control and will not provide the performance of a closed loop system.
Example 3
This is an indirect drive system where the motor to spindle shaft connection may change. This method also provides for
gearing. The encoder is coupled to the spindle shaft to eliminate possible positioning errors. The encoder on the motor
allows for closed loop vector speed control. This method will provide the best indirect positioning performance.
NOTE: This software requires a PG-X2 – Speed Control Card (MagneTek part # DS003) be installed on the drive for
examples 1 and 2. For example 3 a PG-W2 – Dual Encoder Feedback Option Board (MagneTek part # DS014) is
required.
1.0 Wiring
Wire the incoming power, motor, accessories and control wiring as specified in the GPD515 Technical Manual TM4515.
Wire the encoder(s) to the PG-X2 or the PG-W2 according to the instruction sheets 02Y00025-0398 or 02Y00025-0397
respectively.
NOTE: The +12V supply on the PG-W2 card is capable of only 200mA, be sure not to overload it.
