FM-3 Programming Module Reference Manual

Example 2: Rotary Application

This example uses an external sensor and the motor’s encoder marker pulse to establish a

home reference position.

Figure 19: Home Sensor and Marker then Offset, Example

When the device sees the rising edge of the Home Initiate function, it accelerates the motor

to the Home Velocity. The motor continues at that velocity until it first senses the Home

Sensor input. The motor continues on at the home velocity until the marker is activated.

The rising edge of the motor’s encoder marker channel is used to establish the reference

position.

After sensing the rising edge of the motor’s marker channel, the device will continue moving

and will decelerate to a stop at the specified offset position.
