Using low values (e.g. 0.100), can cause FbL trips. To avoid trips, increase Pr 3.56 Speed feedback loss window.
The jog acceleration rate is only used when accelerating towards the jog reference and when changing the jog reference.
The acceleration rate is selected as follows:
0 Ramp rate selection by terminal input
1 - 8 Ramp rate defined by parameter number, i.e. 1 = Pr 2.21 {SE04, 0.25}, 2 = Pr 2.22, etc.
9 Ramp rate selection by Pr 1.50
When Pr 2.20 is set to 0 the deceleration ramp rate selected depends on the state of bit Pr 2.35 to Pr 2.37. These bits are for control by digital inputs
such that ramp rates can be selected by external control. The ramp rate selected depends on the binary code generated by these bits as follows:
When Pr 2.20 is set to 9 the appropriate deceleration rate is automatically selected depending on the value of Pr 1.50, and so a deceleration rate can
be programmed to operate with each reference. Since the new ramp rate is selected with the new reference, the deceleration applies towards the
selected preset if the motor needs to decelerate to reach the preset.
