OUTPUT
589
.xx %
(SRAMP OUTPUT)
Diagnostic, ramp output.
ACCEL OUTPUT
588
.xx %
Accleration diagnostic.
AT SPEED
587
FALSE / TRUE
Diagnostic output indicating the Abs (input - output) is less than AT SPEED LEVEL.
INPUT
574
-100.00 to 100.00 %
Input value.
RATE SELECT
575
0 to 1
Selects between one of two parameter sets. This allows you to have two operating modes
(RATE SET 0 or RATE SET 1) with independent ramp parameters.
AUTO RESET
582
FALSE / TRUE
The ramp is reset automatically when the drive is enabled if set to TRUE.
EXTERNAL RESET
583
FALSE / TRUE
Resets the ramp output.
RESET VALUE
584
-100.00 to 100.00 %
The output value while RESET is TRUE also used as initial value on start up. If this is
linked to speed feedback, the initial ramp output will be set to the current value of speed
feedback.
QUENCH
585
FALSE / TRUE
If TRUE forces the ramp input to zero.
AT SPEED LEVEL
586
0.00 to 100.00 %
Threshold for AT SPEED diagnostic output.
OVER SHOOT
THRESHOLD
591
-100.00 to 100.00 %
(OVERSHOOT THRESH)
Reserved parameter for use by SSD Drives.
ERROR THRESHOLD
592
-100.00 to 100.00 %
Hysterisis level before s-ramp operates.
Reserved parameter for use by SSD Drives.
