When this value is exceeded for theamount of time in P1106, a fault will occur.1106 755 SpdBand IntgrtrSpeed Band IntegerThe amount of time for which the actual speed is allowed to exceed P1105[Speed Dev Band] before a fault occurs.1107 755 Brk Release TimeBrake Release TimeSets the time between the brake release command and when the drive begins toaccelerate. In Encoderless mode, this parameter sets the time to release thebrake after drive starts.1108 755 Brk Set TimeBrake Set TimeDefines the amount of delay time between commanding the brake to be set andthe start of brake proving.1109 755 Brk Alarm TravelBrake Alarm TravelSets the number of motor shaft revolutions allowed during the brake slippagetest. 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 when P1100 [Trq Prove Cfg] Bit 1 “Encoderless” = 1 (enabled).1110 755 Brk Slip CountBrake Slip CountSets the number of encoder counts to define a brake slippage condition. Notused when P1100 [Trq Prove Cfg] Bit 1 “Encoderless” = 1 (enabled).Units: SecsDefault: 10.000Min/Max: 0.500 / 300.000Units:Default:Min/Max:HzRPMP27 [Motor NP Hertz] x 0.0334P28 [Motor NP RPM] x 0.0334P27 x 0.0016 / P27 x 0.25P28 x 0.0016 / P28 x 0.25Units: SecsDefault: 0.060Min/Max: 0.001 / 0.200Units: SecsDefault: 0.100Min/Max: 0.000 / 10.000Units: SecsDefault: 0.100Min/Max: 0.000 / 10.000Default: 1.00Min/Max: 0.00 / 1000.00Default: 250.00Min/Max: 0.00 / 65535.00RW RealRW RealRW RealRW RealRW RealRW RealRW RealPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
