Setting Up Parameters

Master Interpretation

Master Interpretation determines how the incoming pulses are seen to generate the

synchronized motion command. This setting allows you to choose the appropriate signal type

to match the device generating the master input pulses.

Drive Input Signal

Drive Input Signal is selected accordingly based on whether the incoming pulses are

Differential (default) or Single Ended.

Output Source

Output Source determines which signal will be sent to the Sync Output connector on the FM-

3. If Motor Encoder (default) is selected, then the encoder signals from the motor that the

FM-3/En is controlling will be sent out the FM-3 Sync Output connector. If Drive Encoder

Input is selected, then the synchronization signals sent to the Drive 44-pin command

connector will be sent to the FM-3 Sync Output connector. If Module Encoder Input is

selected, then the same signal coming into the FM-3 Sync Input connector will be sent out the

Sync Output connector.

Master Position Setup Group

Define Home Position

Define Home Position is the value that the Master Position Feedback will be set to when the

MasterAxis.DefineHome destination is activated. After the MasterAxis.DefineHome has

been activated, the MasterAxis.AbsolutePosnValid source will activate.

Rotary Rollover Check Box

If checked, the rotary rollover feature for the Master Axis will be enabled.

Rotary Rollover

If enabled, the Master Position will rollover to zero at the value specified here. As the master

encoder counts up, the master position feedback will increase until it reaches the rollover

value and then reset to zero and continue to count up. If rotating in the negative direction, the

master position feedback will decrease until it reaches zero, and then start over at the Rotary

Rollover value.

Master Distance Units

The parameters in this group are used to establish the scaling of the master axis into user units.

Units Name

This is a text string up to 12 characters that will be used to define the units of distance traveled

by the master axis for incoming synchronization signals.
