6.4.1.43 SYSTEM RAMP
This function block forms part of the
reference generation. It provides the
facility to control the rate at which the
inverter will respond to a changing
setpoint demand. MMI Menu Map

Parameter Descriptions Parameter Descriptions
RAMP TYPE RAMP TYPE
Range: Enumerated - see below
Select the ramp type:
Enumerated Value : Ramp Type
0 : LINEAR
1 : S
ACCEL RATE ACCEL RATE Range: 0.0 to 600.0 s
The time that the inverter will take to ramp the setpoint, from 0.00% to 100.00%.
DECEL RATE
DECEL RATE Range: 0.0 to 600.0 s
The time that the inverter will take to ramp from the setpoint, from 100.00% to 0.00%.
SYMETRIC RATE
SYMETRIC RATE Range: 0.0 to 600.0 s
The time that the inverter will take to ramp from 0.00% to 100.00% and from 100.00% to
0.00% when SYMETRIC MODE is TRUE.
SYMETRIC MODE
SYMETRIC MODE Range: FALSE / TRUE
Select whether to use the ACCEL RATE and DECEL RATE pair of ramp rates, or to use
the SYMETRIC RATE parameter to define the ramp rate for the inverter.
RAMP HOLD
RAMP HOLD Range: FALSE / TRUE
When TRUE the output of the ramp is held at its last value.
SRAMP CONTINUOUS
SRAMP CONTINUOUS Range: FALSE / TRUE
When TRUE and the S ramp is selected, forces a smooth transition if the speed setpoint
is changed when ramping. The curve is controlled by the SRAMP ACCEL and SRAMP
JERK 1 to SRAMP JERK 4 parameters. When FALSE, there is an immediate transition
from the old curve to the the new curve.
SRAMP ACCEL
SRAMP ACCEL Range: 0.00 to 100.00 %
Sets the acceleration rate in units of percent per second², i.e. if the full speed of the
machine is 1.25m/s then the acceleration will be:
1.25 x 75.00% = 0.9375m/s²
SRAMP DECEL
SRAMP DECEL Range: 0.00 to 100.00 %
This functions in the same way as SRAMP ACCEL above.
