Parameter Descriptions
INPUT
Range: -300.00 to 300.00%
Ramp input.
ACCEL TIME
Range: 0.0 to 3000.0 s
The time that the Inverter will take to ramp the setpoint from 0.00% to 100.00%.
DECEL TIME
Range: 0.0 to 3000.0 s
The time that the Inverter will take to ramp the setpoint from 100.00% to 0.00%.
SYMMETRIC MODE
Range: FALSE / TRUE
Select whether to use the ACCEL TIME and DECEL TIME pair of ramp rates, or to use the
SYMETRIC RATE parameter to define the ramp rate for the Inverter.
SYMMETRIC TIME
Range: 0.0 to 3000.0 s
The time that the inverter will take to ramp from 0.00% to 100.00% and from 100.00% to
0.00% when SYMMETRIC MODE is TRUE.
HOLD
Range FALSE / TRUE
When TRUE the output of the ramp is held at its last value.
RESET
Range: FALSE / TRUE
If TRUE, the output is made equal to the input.
RESET VALUE
Range: -300.00 to 300.00 %
The value that the output is set to while RESET is TRUE.
OUTPUT
Range: —.00 %
The ramp output.
RAMPING
Range: FALSE / TRUE
This is set TRUE when ramping.
