Chapter 10 Modes of Operation
These two examples show the Zero Speed Threshold using the different speed
command conditions.
• 1: Command source is analog voltage.
The Zero Speed Threshold feature uses the analog speed command
without acceleration/deceleration to determine if this function is
enabled. When the Zero Speed Threshold conditions are met, the motor
speed decelerates to 0 rpm by S-curve deceleration. If not, the motor
follows the analog speed command through S-curve.
• 1: Command source is register.
The Zero Speed Threshold feature uses the register speed command with
acceleration/deceleration to determine if this function should be
enabled. When the Zero Speed Threshold conditions are met, the motor
speed is set to 0 rpm.
For more information on the Zero Speed Threshold feature, see the
Description of Digital Input Functions
on page 433.
