acceleration
time constant
Set the acceleration time constant for the home position return. Set the acceleration
time taken from 0 r/min or 0 mm/s to the rated speed.
When "Use [Pr. PT56] as both acceleration time constant and deceleration time
constant (0 _ _ _)" is selected in [Pr. PT55] Home position return - Deceleration
time constant selection, the value set in this parameter is used as a deceleration
time constant at home position return.
This parameter corresponds to "Homing acceleration (Index: 609Ah)". When this
parameter is mapped for the PDO communication, the value written with Setup
software (MR Configurator2
TM
) is overwritten with the upper side. Thus, do not write
a value with Setup software (MR Configurator2
TM
).
Setting range: 0 to 20000

[ms]
Set the acceleration time constant for the home position return. Set the acceleration
time taken from 0 r/min or 0 mm/s to the rated speed.
When "Use [Pr. PT56] as both acceleration time constant and deceleration time
constant (0 _ _ _)" is selected in [Pr. PT55] Home position return - Deceleration
time constant selection, the value set in this parameter is used as a deceleration
time constant at home position return.
This parameter corresponds to "Homing acceleration (Class ID: 64h, Ins ID: 609Ah,
Attr ID: 0)". When this parameter is mapped for the I/O communication, the value
written with Setup software (MR Configurator2
TM
) is overwritten with the upper side.
Thus, do not write a value with Setup software (MR Configurator2
TM
).
Setting range: 0 to 20000

[ms]
Set the acceleration time constant for the home position return. Set the acceleration
time taken from 0 r/min or 0 mm/s to the rated speed.
When "Use [Pr. PT56] as both acceleration time constant and deceleration time
constant (0 _ _ _)" is selected in [Pr. PT55] Home position return - Deceleration
time constant selection, the value set in this parameter is used as a deceleration
time constant at home position return.
This parameter corresponds to "Homing acceleration (PNU: 24730, Sub: 0)". When
this parameter is mapped for the Process Data communication, the value written
with Setup software (MR Configurator2
TM
) is overwritten with the upper side. Thus,
do not write a value with Setup software (MR Configurator2
TM
).

Home
position
return
deceleration
time constant
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 _ _ _)" of "Home
position return - Deceleration time constant selection" in [Pr. PT55].

PT65
PVC
Profile speed
command
Set the speed of the profile speed command. The fractional portion of the parameter
will be rounded down. The setting value will be clamped at the instantaneous
permissible speed.
This function will be enabled in the profile position mode (pp), Jog mode (jg) and
indexer mode (idx).
This parameter corresponds to "Profile velocity (Index: 6081h)". When this
parameter is mapped for the PDO communication, the value written with Setup
software (MR Configurator2
TM
) is overwritten with the upper side. Thus, do not write
a value with Setup software (MR Configurator2
TM
).
