The jog acceleration rate is only used when the drive starts from the inhibit or ready states, or has reached the jog reference from another
state and the speed is changing because the jog reference is changed. This prevents the fast ramps normally used with jog from being used
when changing between running and jogging.
The deceleration rate is selected as follows.
0 Ramp rate selection by terminal input
1~ 4 Ramp rate defined by parameter number, i.e. 1 = 2.21, 2 = 2.22.
5 Ramp rate selection by parameter 1.50
When parameter 2.10 is set to 0 the deceleration ramp rate selected depends on the state of bit parameters 2.35 to 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 parameter 2.20 is set to 5 the appropriate deceleration rate is automatically selected depending on the value of parameter 1.50, and so
a deceleration rate can be programmed to operate with each preset 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.
Refer to parameter 2.20.
Refer to parameters 6.35 and 6.36 respectively.
The jog deceleration rate is only used when the drive is changing speed because the jog reference has changed or to stop from the jog
reference. It is not used to go from the jog to the run state. This prevents the fast ramps normally used with jog from being used when
changing between running and jogging.
