No. Name and function
PC31 Software limit +
Used to set the address increment side software stroke
PC32
limit. The software limit is made invalid if this value is the
same as in "software limit -".
Set the same sign to [Pr. PC31] and [Pr. PC32]. Setting
of different signs will result in a parameter error.
Set address:
Upper
3 digits
The software limit+ is a set of upper digits and lower
digits. To change the value, set in the order of lower
digits to upper digits.
PC33 Software limit -
Used to set the address decrement side software stroke
PC34
limit. The software limit is made invalid if this value is the
same as in "software limit+".
Set the same sign to [Pr. PC33] and [Pr. PC34]. Setting
of different signs will result in a parameter error.
Set address:
Upper
3 digits
The software limit- is a set of upper digits and lower
digits. To change the value, set in the order of lower
digits to upper digits.
PC35 Internal torque limit 2
Set this parameter to limit servo motor torque on the
assumption that the maximum torque is 100[%].
When 0 is set, torque is not produced.

value
0 PT15 Software limit + (third least significant digit)

PT16
Set an address increasing side of the software stroke
limit.
Upper and lower are a set.
Setting address:
The stop method depends on "Stop method selection at
software limit detection" of [Pr. PD30]. The initial value is
"Quick stop (home position erased)".
Setting a same value with "Software limit -" will disable
the software stroke limit.
Set a same sign for [Pr. PT15] and [Pr. PT16]. A different
sign will be recognized as minus sign data.
When changing the direction to address decreasing,
change it from the - side of the software limit ([Pr. PT17]
and [Pr. PT18]). An incorrect order of the setting will
trigger [AL. 37]. Therefore, cycling power may be
required after [Pr. PT15] to [Pr. PT18] are all set.
Setting range: -999999 to 999999
0 PT17 Software limit - (third least significant digit)
Software limit - (third most significant digit)
PT18
Set an address decreasing side of the software stroke
limit.
Upper and lower are a set.
Setting address:
The stop method depends on "Stop method selection at
software limit detection" of [Pr. PD30]. The initial value is
"Quick stop (home position erased)".
Setting a same value with "Software limit +" will disable
the software stroke limit.
Set a same sign for [Pr. PT17] and [Pr. PT18]. A different
sign will be recognized as minus sign data.
When changing the direction to the address increasing
direction, change it from the + side of the software limit
([Pr. PT15] and [Pr. PT16]). An incorrect order of the
setting will trigger [AL. 37]. Therefore, cycling power may
be required after [Pr. PT15] to [Pr. PT18] are all set.
Setting range: -999999 to 999999
100.0 PC35 Internal torque limit 2
Set the parameter on the assumption that the maximum
torque 100.0 %. The parameter is set for limiting the
torque of the servo motor .
No torque is generated when this parameter is set to
"0.0".
When TL1 (Internal torque limit selection) is turned on,
Internal torque limit 1 and Internal torque limit 2 are
compared and the lower value will be enabled.
Set the parameter referring to section 3.6.1 (5) of "MR-
J4-_A_(-RJ) Servo Amplifier Instruction Manual".
Setting range: 0.0 to 100.0
