RAMP OUTPUT
EXTERNAL RESET
Range: See below
If TRUE, then the ramp is held in reset. EXTERNAL RESET does not depend on AUTO
RESET for its operation.
0 : DISABLED
1 : ENABLED
RESET VALUE
Range: -300.00 to 300.00 %
This value is pre-loaded into the output when RAMP RESET is TRUE, or at power-up. In
order to catch a spinning load smoothly (`bumpless transfer’) connect SPEED FEEDBACK
Tag No. 62 (source) to RESET VALUE Tag No. 422 (destination).
MIN. SPEED
Range: 0.00 to 100.00 %
(MIN SPEED)
The minimum speed clamp is fully bi-directional and operates with a 0.5% hysterisis. This
clamp operates on the input to the ramp and it can therefore be overridden by the RESET
VALUE as far as the ramp output is concerned.
