DRIVE SETUP AND ADJUSTMENT
55
Function # 96
Analog Output 1
Units: Logic
Range 0 - 8
Default: 3
This entry sets the specific analog output
signal to be observed at TB1-46 and TP44.
Selections are:
0 = Calculated CEMF
1 = Raw Speed Command
2 = Ramped Speed command
3 = Encoder Feedback
4 = Armature Current Reference
5 = Measured Armature Current
6 = Measured Armature Voltage
7 = Field current Reference
8 = Measured Field Current
The voltage measured will be a function of the
operating level of the parameter being
displayed and the signal multiplier function 98.
Signal range is limited to and will saturate at
±10V.
Function # 97
Analog Out 0 Multiplier
Units: PU
Range: 0.10 – 10.00
Default: 0.80
This entry sets the specific multiplier value for
Analog Output #0. A value of 0.8 will set 8.0
volts of output for a 1 per unit signal, with
some headroom to show over-scale.
Function # 98
Analog Out 1 Multiplier
Units: PU
Range: 0.10 – 10.0
Default: 0.80
This entry sets the specific multiplier value for
Analog Output #1. A value of 0.8 will set 8.0
volts of output for a 1 per unit signal, with
some headroom to show over-scale.
Function # 99
Speed Error Trip Time
Units: SEC
Range: 0.20 – 5.00
Default: 5.00
This value sets the time sensitivity of the
Speed Error Trip detection function. Speed
errors larger than function 100, for longer than
function 99 seconds will cause a Speed Error
Trip and automatic drive shut down with Fault
F410.
Function # 100
Speed Error Trip Threshold
Units: %
Range 0.0 - 100.0
Default: 100.0
This value sets the magnitude sensitivity of
the Speed Error Trip detection function.
Speed errors larger than function 100, for
longer than function 99 seconds will cause a
Speed Error Trip and automatic drive shut
down with Fault F410.
Function # 101
Auto Fault Reset
Units: Logic
Range: 0 (Off) - 1 (On)
Default: 0 (Off)
This function allows the Drive to automatically
reset drive faults that caused a shutdown
without an external Fault Reset command.
When turned ON, the drive will attempt an
automatic fault reset 5 seconds after the fault
occurs. If successful, the drive may then be
restarted. This feature is made inoperable by
setting function 101 to 0 (off).
Note: A Fault count total is accumulated.
One fault count is removed from the total
every 20 minutes. An accumulation of 5
counted faults will cause fault 411 Maximum
Resets Attempted and the need for a manual
reset for continued operation.
Function # 102
3 Second Loop Fault
Units: Logic
Range: 0 (Off) – 1 (On)
Default: 0 (Off)
This function selects the detection time for
loop contactor faults. These occur when the
contactor acknowledge feedback contact fails
to open or close according to the commanded
state of the contactor coil driver. Small
contactors should operate within 450
milliseconds and should use the default value,
0, or OFF. If large contactors are used with
large hp drives, set this value to ON to yield a
3 second fault detection time.
Function # 104
Serial Gain Switch
Units: Logic
Range: 0 (Off) – 1 (On)
Default: 1(On)
This function selects the source of the gain
switch control to be from local or serial link
commands. If an analog reference velocity or
