Hold Timer
The function of this parameter only applies to LF.30 = 5 Synthetic pre-torque.
This timer inserts dead time prior to brake release during which the current check
function occurs and the motor becomes magnetized. In this case it should always
be adjusted less than the actual mechanical brake pick time.
Unit: 0.1 seconds
Value range: 0.0...10.0
Default setting: 0.4
Adjustment values: (when LF.30 = 5) 1/2 of the total speed pick delay
time but less than the mechanical brake pick time
Refer to section 5.12.4 for additional information on adjustment.
The function of this parameter only applies to LF.30 = 5 synthetic pre-torque.
This timer controls the window during which the synthesized pre-torque function
is actually active. The mechanical release of the brake must take place during
this time period.
Unit: 0.1 seconds
Value range: 0.0...10.0
Default setting: 0.1
Adjustment values: (when LF.30 = 5) 0.1 to 0.2
Refer to section 5.12.4 for additional information on adjustment.
