Torque Prove

1100 Trq Prove Cfg

Torque Prove Configure

RW 16-bit

Integer

Enables/disables torque/brake proving function. When “Enabled,” brake control comes from a digital output relay that is set to select Port 0, P1103 [Trq Prove

Status] Bit 4 “Brake Set.” Refer to the PowerFlex 750-Series AC Drives Reference Manual, publication 750-RM002

, for examples on how to use Torque Prove with

PowerFlex 755 drives.

Bit 0 “TP Enable” – Enables TorqProve functions.

Bit 1 “Encoderless” – Enables encoderless operation – Bit 0 must also be enabled. Read the Attention statement under Lifting/Torque Proving on page 360

Bit 2 “Micro Psn” – Enables the Micro Position digital input to change the speed command by the value set in P1112 [MicroPsnScalePct] while the drive is running.

Bit 3 “Preload” – “0” uses the last torque for preload. “1” uses “TorqRef A” if commanded direction is forward and “TorqRef B” for reverse.

Bit 4 “FW LoadLimit” – Enables drive to perform load calculation at base speed. Drive will then limit operation above base speed depending on load.

Bit 5 “BrkSlipEncls” – A “1” Disables the partial Brake Slip routine from the drive when encoderless is selected.

Bit 6 “BrkSlipStart” – Starts drive if Brake slippage is detected.

Bit 7 “Test Brake” – Tests the brake at Start. Torque is applied against the brake while movement is monitored.

Bit 8 “Fast Stop Bk” – Brake is set immediately upon receiving a Fast Stop input vs. setting the brake after the ramp.

Bit 9 “BkSlp SpdLmt” – When a brake slip condition is detected, the load is lowered at a fixed speed (Preset Speed 1).

1101 Trq Prove Setup

Torque Prove Setup

RW 16-bit

Integer

Allows control of specific torque proving functions through a communication device.

Bit 0 “Fast Stop” – Forces a current limit stop.

Bit 1 “Float Micro” – Activates the micro position function when selected and running. Activates float when stopping.

Bit 2 “Decel Fwd” – Forces decel forward travel limit.

Bit 3 “End Stop Fwd” – Forces end forward travel limit.

Bit 4 “Decel Rev” – Forces decel reverse travel limit.

Bit 5 “End Stop Rev” – Forces end reverse travel limit.

Bit 6 “PHdwrOvrTrvl” – Positive Hardware Over Travel limit: Setting this bit creates a Coast to Stop fault.

Bit 7 “NHdwrOvrTrvl” – Negative Hardware Over Travel limit: Setting this bit creates a Coast to Stop fault.

1102 DI FloatMicroPsn

Digital Input Float Micro Position

Selects the digital input to be used for the float and micro position functions. Activates

the micro position function when selected and running. Activates float when stopping.
