CMPx.ARM

Description

Use this keyword to arm or disarm a Compare setpoint. The setpoint value will only be compared against the Compare source (CMPx.SOURCE) if that setpoint is armed. If they match, an output pulse will be generated.

An error will be generated if CMPx.SOURCE, CMPx.MODBOUND1, CMPx.MODBOUND2, CMPx.WIDTH, and CMPx.MODEN are not set prior to enabling CMPx.ARM. If CMPx.SETPOINT is not set prior to enabling CMPx.ARM, the compare will trigger at the last set value, or the default value of 0 if the drive has been power cycled.

When accessing this keyword through a fieldbus, the values are to be interpreted as a bitmask, with each bit corresponding to one of the Compare setpoints.

Example

The following example arms setpoint 3 for CMP1.

-->CMP1.ARM 3 1
