(All Operating Modes)
Parameter No. Parameter
name
Explanation Reference
Pn402 Forward torque
limit
Set the output torque limit for the forward direction
as a percentage of the rated torque (setting range:
0% to 800%).
4-4-4 Parameter
Details
Pn403 Reverse torque
limit
Set the output torque limit for the reverse direction
as a percentage of the rated torque (setting range:
0% to 800%).
Note 1. Set these parameters to 350 (the default setting) when the torque limit function is not being
used.
Note 2. If the connected Servomotor is set to a value greater than the maximum momentary torque,
the maximum momentary torque will become the set limit.
D Limiting Operation with External Signals (All Operating Modes)
Parameter No. Parameter name Explanation Reference
Pn50b.2
Pn50b.3
Input signal selection 2
PCL signal selection
NCL signal selection
You must allocate PCL and NCL. (See note 1.) 4-4-3 Important
Parameters
Pn404 Forward torque limit Set the output torque limit when PCL is ON as
a percentage of the Servomotor rated torque
(setting range: 0% to 800%).
4-4-4
Parameter
Details
Pn405 Reverse torque limit Set the output torque limit when NCL is ON as
a percentage of the Servomotor rated torque
(setting range: 0% to 800%).
Note 1. If you change the default settings, set Pn50A.0 (input signal selection mode) to 1.
Note 2. If the connected Servomotor is set to a value greater than the maximum momentary torque,
the maximum momentary torque will become the set limit.
Note 3. If using this function with internally-set speed control, set Pn50A.1 to 1 (user-defined set-
tings), and allocate the required input signals (PCL, NCL, SPD1, SPD2, RDIR, etc.)
D Limiting Normal Operation with Analog Voltage (Position, Speed, Internally-set
Speed Control)
• When Pn002.0 (torque command input switching) is set to 1, TREF (torque command input) becomes
the analog torque limit input terminal, so you can limit the torque on multiple levels.
• Calculate the torque limit (%) as follows: Absolute TREF voltage (V) / Pn400 (torque control scale) x
1000.
• Regardless of whether the voltage is positive or negative, both forward and reverse directions have
the same limits (i.e., absolute value is taken).
