Time for CANopen Quick Stop

Settings
 Use this to set the time to decelerate from the maximum operation frequency (Pr.01-00) to 0.00
Hz by CANopen control.
Regenerative Energy Restriction Control Method

Settings
 0: decelerate or stop in accordance with the original deceleration setting.
 1: during deceleration, the drive controls the motor according to the setting of Pr.06-01 and the
voltage recovery rate of the DC BUS. The controller starts when the DC BUS voltage reaches
95% of Pr.06-01. When Pr.06-01 is set to 0, the drive controls the motor according to the
operating voltage and the voltage recovery rate of the DC BUS. This method decelerates
according to the setting for the deceleration time. The fastest actual deceleration time is not less
than the deceleration time setting.
 2: during deceleration, the drive controls the motor according to the setting of Pr.06-01 and the
voltage recovery rate of the DC BUS. The controller starts when the DC BUS voltage reaches
95% of Pr.06-01. This function can auto-tune output frequency and output voltage to accelerate
consumption of DC BUS energy according to drive's ability, so that the actual deceleration time
can comply with the parameter setting. Use this setting when over-voltage occurs due to
unexpected deceleration time.
Deviation Value of TEC Action Level
Settings
 When the regenerative energy restriction is set as Traction Energy Control (TEC) (Pr. 01-49 = 2),
and the DC BUS reaches the over-voltage stall prevention (Pr. 06-01) minus the deviation value
of TEC action level (Pr. 12-08), the regenerative energy restriction activates. Use Pr. 12-08 to
control the action level of this function.
Deviation Value of TEC Stop
Settings
When the regenerative energy restriction activates, and the DC BUS reaches the start-up level

minus the deviation value of TEC stop (Pr. 12-09), the regenerative energy restriction stops. Use
Pr. 12-09 to control the stop level of this function
Pr. 01-45 = 0: 0.00–600.00 sec.
Pr. 01-45 = 1: 0.0–6000.0 sec.
0: Disable
1: Over voltage energy restriction
2: Traction energy control (TEC)
