138 ACE-tronics G9 ASD Installation and Operation Manual
Auto Restart Selection
Program Protection Retry/Restart
This parameter Enables/Disables the ability of the ASD to start into a spinning
motor when the ST activation ceases (if so configured; see
F110) momentarily
and is then reactivated (ST deactivation/ST activation) or after a power
interruption (momentary power failure).
Settings:
Off
Enabled (at Power Failure)
Enabled (at ST Activate/Deactivate)
Enabled (at ST Activate/Deactivate or Power Failure)
Enabled (at Run)
Direct Access Number — F301
Parameter Type — Selection List
Factory Default — Off
Changeable During Run — No
Regenerative Power Ridethrough
Program Protection Under-Voltage/Ridethrough
This parameter determines the motor-control response of the ASD in the event
of a momentary power outage or under-voltage condition.
During a Ridethrough, regenerative energy is used to maintain the control
circuitry settings for the duration of the Ridethrough; it is not used to drive the
motor. The motor(s) of the system are stopped and then restarted automatically
if so configured.
In a multiple-motor application, there will be a requirement to synchronize the
stopping and restarting of the motors as not to cause breakage in the product
being processed by the motors stopping/starting at different times (e.g., wire
spools, bobbin winder for textile machines, etc.). Parameters
F317 and F318
must be setup to synchronize motor operation as to avoid breakage in these
types of applications.
Note: If used to restart the motors, the Retry setup of F301 is required.
Note: The Jog function will not operate while in the Synchronized
Decel/Accel mode.
Settings:
Off
Ridethrough On
Decel Stop
Synchronized ACC/DEC (TB)
Synchronized ACC/DEC (TB + Power Off)
Ridethrough Setup Requirements
1. Select the Ridethrough Mode at F302.
2. Select the Ridethrough Time at F310.
3. Select the Synchronized Stop/Start Times at F317/F318 (if required).
Note: F317 and F318 are not functional while operating in the Torque
or Position control modes, or for the Jog Run function (F260).
4. Set a discrete input terminal to Power Failure Synchronized Signal and
activate the terminal to enable the Synchronized Accel/Decel function.
5. Select the Ridethrough Control Level at F629.
