606 [Float Tolerance]
Sets the frequency level where the float timer
starts. Also sets the frequency level where the
brake will be closed in Encoderless TorqProve
mode.
Default:
Min/Max:
Units:
0.2 Hz
6.0 RPM
0.1/5.0 Hz
3.0/150.0 RPM
0.1 Hz
0.1 RPM
607 [Brk Set Time]
Defines the amount of delay time between
commanding the brake to be set and the start of
brake proving.
Default:
Min/Max:
Units:
0.10 Secs
0.00/10.00 Secs
0.01 Secs
608 [TorqLim SlewRate]
Sets the rate to ramp the torque limits to zero
during brake proving.
Default:
Min/Max:
Units:
10.0 Secs
0.5/300.0 Secs
0.1 Secs
609 [BrkSlip Count]

brake slippage condition. Not used in
encoderless operation.
Default:
Min/Max:
Units:
250
0/65535
1
610 [Brk Alarm Travel]
Sets the number of motor shaft revolutions
allowed during the brake slippage test. Drive
torque is reduced to check for brake slippage.
When slippage occurs, the drive allows this
number of motor shaft revolutions before
regaining control. Not used in Encoderless
TorqProve mode.
Default:
Min/Max:
Units:
1.0 Revs
0.0/1000.0 Revs
0.1 Revs
611 [MicroPos Scale%]
Sets the percent of speed reference to be used
when micropositioning has been selected in
[TorqProve Cnfg]. Bit 2 of [TorqProve Cnfg],
parameter 600 determines if the motor needs to
come to a stop before this setting will take effect.
Default:
Min/Max:
Units:
10.0%
0.1/100.0%
0.1%
…
612 [Torq Prove Sts]
Displays the status bits for TorqProve.
