The PostRampReference (02.001) is combined with HardFrequencyReference (03.022) and the slip compensation frequency to define the output
frequency of the drive. The PostRampReference (02.001) is defined by the output of the ramp system except when the current limits are active (see
Menu 04).
Parameter 02.003 Ramp Hold
Short description Set to 1 to hold the ramp system at its present value

If RampHold (02.003) = 0 the ramp system functions normally. If RampHold (02.003) is set to 1 and SRampEnable (02.006) = 0 the ramp system
output is held at its current level. If RampHold (02.003) is subsequently set to 0 the ramp system output is released and continues to operate normally.
If SRampEnable (02.006) = 1 when RampHold (02.003) is set to 1 the acceleration will ramp towards zero and the frequency will change in an S
curve towards a constant frequency. If a drive stop is requested (i.e. ReferenceOn (01.011) = 0) the ramp hold function is disabled.
