16-bit
Integer
Displays the status bits for TorqProve.
Bit 0 “EndLimitActv” – End travel limit active.
Bit 1 “DecelLmtActv” – Decel travel limit active.
Bit 2 “Micro Psn” – Micro position active.
Bit 3 “BrkSlip1 Alm” – Brake slip detected.
Bit 4 “Brake Set” – Brake signal set. For example set P10 [RO0 Sel] on the digital I/O module to Port 0, P1103 Bit 4 and set P6 [Dig Out Invert] Bit 0 = 1.
Bit 5 “LoadTestActv” – The test used to check the load for above base speed operation is active.
Bit 6 “RefLoadLmted” – The reference is limited due to the load test results.
Bit 7 “Encoderless” – Encoderless configure fault is active.

Speed Dev Band
Speed Deviation Band
The amount of allowable deviation between the commanded speed and the actual
speed (from a feedback device). When this value is exceeded for the amount of time in
P1106 [SpdBand Intgrtr], a fault will occur.

Brk Release Time
Brake Release Time
With an encoder, this parameter sets the time between the brake release command and
when the drive begins to accelerate.
Without an encoder, this parameter sets the time to release the brake after drive starts.

start of brake proving.

Brk Alarm Travel
Brake 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 when P1100
[Trq Prove Cfg] Bit 1 “Encoderless” = 1 (enabled).
Default:
Min/Max:

Brk Slip Count
Brake Slip Count
Sets the number of encoder counts to define a brake slippage condition and is based on
the feedback device attached to P135 [Position Feedback]. Not used when P1100 [Trq
Prove Cfg] Bit 1 “Encoderless” = 1 (enabled).
