690+ Series Frequency Inverter
REFERENCE 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.

Parameter Descriptions
RAMP TYPE
Range: Enumerated - see below
Select the ramp type:
Enumerated Value : Ramp Type
0 : LINEAR
1 : S
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%.
SYMETRIC 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.
SYMETRIC 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 SYMETRIC MODE is TRUE.
SRAMP ACCEL
Range: 0.00 to 100.00 /s²
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
Range: 0.00 to 100.00 /s²
This functions in the same way as SRAMP ACCEL above.
