3-34 Programming and ParametersFileGroupValuesRead-WriteData TypeNameNo. Description191 DI PID EnableDigital Input Proportional Integral Derivative EnableAssigns a digital input used to activate the Process PID control.192 DI PID HoldDigital Input Proportional Integral Derivative HoldAssigns a digital input used to hold the Process PID integrator.193 DI PID ResetDigital Input Proportional Integral Derivative ResetAssigns a digital input used to reset the Process PID integrator.194 DI PID InvertDigital Input Proportional Integral Derivative InvertAssigns a digital input used to invert the output of the Process PID control.Default: 0Min/Max: 0 / 159999.15RW 32-bitIntegerDefault: 0Min/Max: 0 / 159999.15RW 32-bitIntegerDefault: 0Min/Max: 0 / 159999.15RW 32-bitIntegerDefault: 0Min/Max: 0 / 159999.15RW 32-bitInteger195 DI Torque StptADigital Input Torque Setpoint AAssigns a digital input used to force P676 [Trq Ref A Stpt] as the source forTorque Reference A, regardless of the setting in P675 [Trq Ref A Sel]. Used whenthe drive is in a mode that is commanding torque (see P309…P312).Default: 0Min/Max: 0 / 159999.15RW 32-bitInteger196 DI Fwd End LimitDigital Input Forward End LimitAssigns a digital input used to trigger a Forward End Limit. The resulting action isto execute a “Fast Stop” command. After the drive stops in this case, it will onlyrestart in the opposite direction. This function is usually used with a limit switchnear the point at which the drive should stop.Default: 0Min/Max: 0 / 159999.15RW 32-bitIntegerFEEDBACK & I/ODigin Functions197 DI Fwd Dec LimitDigital Input Forward Deceleration LimitAssigns a digital input used to trigger a Forward Decel Limit. The resulting actionis to override the speed reference and decelerate to Preset Speed 1. Thisfunction is usually used with a limit switch and initiates the slowing down processprior to encountering the End Limit.198 DI Rev End LimitDigital Input Reverse End LimitAssigns a digital input used to trigger a Reverse End Limit. The resulting action isto execute a “Fast Stop” command. After the drive stops in this case, it will onlyrestart in the opposite direction. This function is usually used with a limit switchnear the point at which the drive should stop.Default: 0Min/Max: 0 / 159999.15Default: 0Min/Max: 0 / 159999.15RW 32-bitIntegerRW 32-bitInteger199 DI Rev Dec LimitDigital Input Reverse Deceleration LimitAssigns a digital input used to trigger a Reverse Decel Limit. The resulting actionis to override the speed reference and decelerate to Preset Speed 1. Thisfunction is usually used with a limit switch and initiates the slowing down processprior to encountering the End Limit.Default: 0Min/Max: 0 / 159999.15RW 32-bitInteger200 DI PHdwr OvrTrvlDigital Input Positive Hardware Over TravelAssigns a digital input used to trigger a Positive Hardware Over-travel. Theresulting action is to immediately fault and produce zero torque. After the drivestops in this case, the fault will need to be reset, and the drive will only restart inthe opposite direction. This function is usually used with a limit switch in aposition beyond the “End Limit,” as an extra safety limit to prevent torque fromdamaging the machine in an over-travel situation.201 DI NHdwr OvrTrvlDigital Input Negative Hardware Over TravelAssigns a digital input used to trigger a Negative Hardware Over-travel. Theresulting action is to immediately fault and produce zero torque. After the drivestops in this case, the fault will need to be reset, and the drive will only restart inthe opposite direction. This function is usually used with a limit switch in aposition beyond the “End Limit,” as an extra safety limit to prevent torque fromdamaging the machine in an over-travel situation.Default: 0Min/Max: 0 / 159999.15RW 32-bitIntegerDefault: 0Min/Max: 0 / 159999.15RW 32-bitIntegerPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
