AC890PX AC Drive
The Start/Stop Mode Explained
The default configuration below shows the drive in Remote control, (using the analog and digital inputs and outputs). This
example will be referred to in the following explanations.
Start/Stop Controlled Remotely
In the configuration shown, the reference value is obtained by summing ANALOG INPUT 1 and ANALOG INPUT 2. The
direction of rotation is controlled by DIGITAL INPUT 4. When the RUN input (DIGITAL INPUT 1) is TRUE, the SPEED
DEMAND ramps up to the reference value at a rate controlled by ACCEL TIME. The drive will continue to run at the
reference value while the RUN input remains TRUE.
Similarly when the JOG input (DIGITAL INPUT 5) is TRUE, the SPEED DEMAND ramps up to the JOG SETPOINT at a
ramp rate set by JOG ACCEL TIME (not shown in the diagram).
The drive will continue to run at the JOG SETPOINT while the JOG input remains TRUE.
