HSB Deceleration Frequency Width

Sets the amount by which the output frequency is to be lowered during high-slip braking, as a percentage of E1-04 [Maximum Output Frequency], which represents the 100% value.

HSB Current Limit Level

Sets the maximum current output during high-slip braking as a percentage, where E2-01 [Motor Rated Current (FLA)] is 100%. Also set the current suppression to prevent exceeding drive overload tolerance.

Note:

The upper limit to the setting range changes when the setting for C6-01 [Normal / Heavy Duty Selection] changes.

  • 150% when C6-01 = 0 [Heavy Duty Rating]

  • 110% when C6-01 = 1 [Normal Duty Rating]

HSB Dwell Time at Stop

Sets the dwell time, a length of time when high-slip braking is ending and during which the motor speed decreases and runs at a stable speed. For a set length of time, the drive will hold the actual output frequency at the minimum output frequency set in E1-09.

HSB Overload Time

Sets the time used to detect oL7 [High Slip Braking Overload], which occurs when the output frequency does not change during high-slip braking. Usually it is not necessary to change this parameter.
