5. PARAMETERS
No./ Setting
symbol/name digit
PT53 Set the rate of change of the torque command per second.
TQS However, setting "0.0" will disable the torque slope.
Torque slope This function will be enabled in the profile torque mode.
This parameter corresponds to "Torque slope (6087h)". When mapped using PDO, it
may not be written with MR Configurator2.
Setting range: 0.0 to 1000000.0
PT55 _ _ _ x Home position return - Deceleration time constant selection
*TOP8 Set a value used for the acceleration time constant and deceleration time constant at
home position return.
Function
selection T-8 0: Using [Pr. PT56] for both acceleration time constant and deceleration time
constant
1: Using [Pr. PT56] for acceleration time constant, and [Pr. PT57] for deceleration
time constant

x _ _ _
PT56 Set the acceleration time constant for the home position return. Set an acceleration
time from 0 r/min or 0 mm/s to the rated speed.
HMA
This function will be enabled in the cyclic synchronous mode and profile mode.
Home
position The parameter is used as a deceleration time constant for the home position return
return when you select "Using [Pr. PT56] for both acceleration time constant and
acceleration deceleration time constant (0 _ _ _)" of "Home position return - Deceleration time
time constant constant selection" in [Pr. PT55].
This parameter corresponds to "Homing acceleration (609Ah)". When mapped using
PDO, it may not be written with MR Configurator2.
Setting range: 0 to 20000
PT57 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.
HMB
This function will be enabled in the cyclic synchronous mode and profile mode.
Home
position The parameter will be enabled when you select "Using [Pr. PT56] for acceleration
return time constant, and [Pr. PT57] for deceleration time constant (1 _ _ _)" of "Home
deceleration position return - Deceleration time constant selection" in [Pr. PT55].
