12.1-01-15

12-10
TEC Voltage Compensation Filter Time
Default: 1.000
Settings 0.000–65.535 sec.
 Adjust the output voltage filter time of the regenerative energy restriction.

01-50
Electromagnetic Traction Energy Consumption Coefficient
Default: 0.50
Settings 0.00–5.00 Hz
 During acceleration / steady speed / deceleration, the drive will dynamically adjust the output
voltage based on the DC bus voltage level in order to prevent the drive from tripping on over-
voltage. The output voltage is adjusted based on this parameter setting.
 The drive's output current and the efficiency of regenerative energy consumption increase when
Pr.01-50 is increased. When Pr.01-50 is decreased, also the drive's output current and the
efficiency of regenerative energy consumption will decrease.
 When setting Pr.01-50, pay attention to the drive’s output current. The drive’s output current must
be lower than 80% of the motor’s rated current to prevent the motor from overheating.

01-51
Flux-Weakening Overload Stall Prevention Time
Default: 1.00
Settings 0.00–600.00 sec.
 The parameter is valid only when the speed control mode is SynRM sensorless control (Pr.00-
11=8).
 When the motor drive operates in flux-weakening region and the load of the motor driven by the
motor drive suddenly increases, and cause the motor to slow down, you can adjust the
parameter if the speed of motor oscillates or OC error occurs.
01-52
Zero-Speed Delay Time
Default: 0
Settings 0–65535
01-53
Zero-Speed Delay Level
Default: 1.00
Settings 0.00–599.00 Hz
 This function applies to IMFOCPG and IMFOC control modes.
 In application for large inertia or rapid deceleration, it often occurs that the frequency command
programs decelerating to the minimum frequency, the drive stops outputting at that moment, but
the motor’s actual speed has not reached zero-speed yet, therefore, the motor goes to free-run
status. The zero-speed delay function refers to the actual (or estimated) rotor frequency, it
counts the setting time of Pr.01-52 after the actual (or estimated) rotor frequency reaches the
setting level of Pr.01-53, then the drive stops outputting.
