670 [Adj Volt Trim Hi]
Scales the upper value of the [Adj Volt TrimSel]
selection when the source is an analog input.
Default:
Min/Max:
Units:
100.0%
0.0/100.0% of Drive Rated Volts
0.1%
671 [Adj Volt Trim Lo]
Scales the lower value of the [Adj Volt TrimSel]
selection when the source is an analog input.
Default:
Min/Max:
Units:
0.0%
0.0/100.0% of Drive Rated Volts
0.1%
672 [Adj Volt Trim %]
Scales the total voltage trim value from all
sources. Analog In 1 & 2 are scaled separately
with [Adj Volt Trim Hi] & [Adj Volt Trim Lo] then
[Adj Volt Trim %] sets the trim value. The sign of
this value will determine if trim is added or
subtracted from the reference.
Default:
Min/Max:
Units:
0.0%
–/+100.0% of Drive Rated Volts
0.1%
675 [Adj Volt AccTime]
Sets the rate of voltage increase. The value will
be the time it takes to ramp the voltage from
[Min Adj Voltage] to [Maximum Voltage]. An “S”
curve can be applied to the ramp using
parameter 677.
Default:
Min/Max:
Units:
0.0 Secs
0.0/3600.0 Secs
0.1 Secs
676 [Adj Volt DecTime]
Sets the rate of voltage decrease. The value will
be the time it takes to ramp the voltage from
[Maximum Voltage] to [Min Adj Voltage]. An “S”
curve can be applied to the ramp using [Adj Volt
Scurve]. Important: This ramp and [Decel Time
1/2] (parameters 142/143) must ramp to zero for
drive to Stop.
Default:
Min/Max:
Units:
0.0 Secs
0.0/3600.0 Secs
0.1 Secs
677 [Adj Volt S Curve]
Sets the percentage of accel or decel time to be
applied to the voltage ramp as “S” curve. Time is
added 1/2 at the beginning and 1/2 at the end.
Default:
Min/Max:
Units:
0.0%
0.0/100.0%
0.1%
