Limiting the Speed to a Constant Speed in Torque Control Mode
Limiting the Speed with Analog Voltage
• This function limits Servomotor rotation speed when torque control is used.
• Set a limit so that the Servomotor rotation speed does not exceed the maximum speed of the
• Outside of the speed limit range, a torque in proportion to the difference from the speed limit value
• There are two methods that can be used for limiting the speed:
• The speed will be limited according to the following parameter setting if the Torque Command/
• The Speed Command Input (REF) will be the Analog Speed Limit Input terminal if the Torque
The default setting for Pn50 is 300, so the speed will be 3,000 r/min for an input of 10 V.
mechanical system.
is generated to slow down the Servomotor rotation speed. In such cases the number of
Servomotor rotations does not necessarily match the speed limit value. (The number of
Servomotor rotations varies depending on the load.)
Speed Limit Selection (Pn5B) is set to 0.
Command/Speed Limit Selection (Pn5B) is set to 1. Therefore, the speed can be limited on
multiple levels.
• Apply a constant fixed speed limit in Torque Control Mode (parameter settings).
• Limit the speed with an analog voltage.
The speed is limited using the No. 4 Internally Set Speed (Pn56).
Use the Speed Command Input (REF) as an Analog Speed Limit Input (VLIM).
