5.2 Detailed list of parameters
Function
Set the deceleration time constant at the home position return. Set a deceleration time from the rated speed
to 0 r/min or 0 mm/s.
The parameter will be enabled when you select "Using [Pr. PT56] for acceleration time constant, and [Pr.
PT57] for deceleration time constant (_ _ _ 1)" in [Pr. PT55] Home position return - Deceleration time
constant selection.
Setting range: 0 to 20000
Set a maximum speed for the torque mode.
With equipment for the simple motion connected, writing from MR Configurator2 may not be reflected since
this parameter is updated by the simple motion.
Setting range: 0.00 to instantaneous permissible speed
Set the extension parameter of [Pr. PT07].
When [Pr. PT69] is used, the home position shift distance can be calculated as follows.
Home position shift distance = [Pr. PT07] + ([Pr. PT69]  65536)
This parameter setting is available with servo amplifiers with software version A1 or later.
Setting range: 0 to 32767
Set the extension parameter of [Pr. PT09].
When [Pr. PT71] is used, the travel distance after proximity dog can be calculated as follows.
Travel distance after proximity dog = [Pr. PT09] + ([Pr. PT71]  65536)
This parameter setting is available with servo amplifiers with software version A1 or later.
Setting range: 0 to 32767
