B611: Over Speed Protection Level (%)
This is the over speed protection level. When the detection speed is equal to or higher than the set
level for 1000msec, the unit will trip in over speed fault. Set as a percentage of maximum frequency.
B612: Speed Deviation Level (%)
This is the speed deviation level. A speed deviation error occurs when the speed command and
speed detection difference is higher than the set level (B612) for B626 time. Set as a percentage of
maximum frequency.
B613: Machine Time Constant (mS)
The time to accelerate the motor and load's torque inertia to the base speed at the rated torque is set.
B614: Acceleration Machine Bias (%)
This adds fixed bias in speed PID output during acceleration.
B615: Deceleration Machine Bias (%)
This adds fixed bias in speed PID output during deceleration.
B620: ASR Gain Change Frequency 1 (Hz)
Gain change frequency for low speed.
B621: ASR Gain Change Frequency 2 (Hz)
Gain change frequency for high speed.
B623: Encoder Low Pass Filter Time Constant (ms)
The speed detection noise is cut at the set time constant. These parameters are applicable for close
loop V/F and close loop vector control.
B626: Speed Deviation Fault Judgment Time (Sec)
A speed deviation fault occurs when the speed command and speed detection difference is the same
or higher than the speed deviation level (B612), and this situation continues for longer than the speed
deviation fault judgment time (B626).
