Electromagnetic energy traction control activates in the following three conditions:
1. Activates when DC bus is larger than the over-voltage stall prevention level (Pr.06-01) during
acceleration and deactivates once Pr.06-01 is disabled.
2. Activates when DC bus is larger than the over-voltage stall prevention level (Pr.06-01) during
steady operation and deactivates once Pr.06-01 is disabled.
3. Activates during deceleration (including stop) and deactivates once acceleration occurs or
deceleration is stopped.
When Pr.01-49=3, Pr.06-02=1 (Smart Over-voltage Stall Prevention) is automatically set to
increase the stability during deceleration.

12-08
Deviation Value of TEC Action Level
Default: 15.0
Settings 0.0–120.0 V
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.
12-09
Deviation Value of TEC Stop
Default: 15.0
Settings 0.0–120.0 V
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.
