Parameter Name and Description
DRIVE
PROTECT
(Continued)
FOLLOWING ERROR
(2202)
Only available or active in either
Vector mode. Ignore for V/F
mode.
Preset Value: 0
Range: 0 - 1
Off (0) Control ignores “At Speed Error” from the process.
On (1)
Control monitors the following error from the process. If the process speed is
outside the range set in the Level 1 Output block, At Speed Band parameter,
the drive will fault and will disable.
TORQUE PROVING (2203)
Only available or active in either
Vector mode. Ignore for V/F
mode.
Preset Value: 0
Range: 0 - 1
Off (0) Control ignores unbalanced motor phases.
On (1)
Control looks for balanced output current in all three phases to the motor.
Unbalanced output current will cause a trip and create a torque proving fault.
This occurs after establishing flux current in the motor.
FEEDBACK LOSS (2204)
Only available in Closed Vector
mode. Ignore for Open Vector and
V/F modes.
Preset Value: 1
Range: 0 -1
Off (0) Loss of feedback signal is ignored.
On (1) Loss of feedback signal produces a trip condition to disable the drive.
FOLDBACK GAIN
(2205)
Only available or active in V/F
mode. Ignore for Vector modes.
Preset Value: 0.010
Range: 0.000 - 10.000
Sets the rate of change of output frequency during current limit.
OVERLOAD (2206) Preset Value: 0
Range: 0 - 2
Fault (0) Drive will fault and disable PWM to motor if overload capability is exceeded.
Foldback (1) Drive attempts to reduce current to 80% of Drive rated current so that time
remaining can count back up.
Hold (2) Drive attempts to reduce current to 100% of drive rated current so that time
remaining can hold at present value.
Sets how the control handles I
2
T power overloads. When an overload occurs
it will either Fault, Foldback, or Hold based on the control output AMPS.
OVERLOAD TRIGGER (2207)
Only available or active in V/F
mode. Ignore for Open Vector
mode.
Preset Value: 50.0
Range: 0.0 - 100.0%
Sets the trigger point for an overload condition.
ENCODER SENSE (2208)
Only available in Closed Vector
mode. Ignore for Open Vector and
V/F modes.
Preset Value: 1
Range: 0 -1
Manual (0) Encoder direction is set by Level 1 block, Motor Control, Feedback Align
parameter.
Automatic (1) Allows the control to automatically sense encoder direction at power up after
a Restore Factory Settings.
