5 Operation
5.5.3 Speed Limit in Force Control
(1) Signals Output during Servomotor Speed Limit
The following signal is output when the motor speed reaches the limit speed.
Type
Output
For use, this output signal must be allocated with Pn50F. For details, refer to 3.3.2 Output Signal Allocations.
(2) Speed Limit Mode Selection (Force Limit Option)
Select the speed limit mode with Pn002.
Pn002
(3) Internal Speed Limit Function
If the internal speed limit function is selected in Pn002, set the limit of the maximum speed of the motor in
Pn480.
The limit of the speed in Pn408 can be selected from the maximum speed of the motor or the overspeed detec-
tion speed.
Pn480
Note:
• The servomotor's maximum speed will be used when the setting in this parameter exceeds the maximum speed of
Pn408
(4) External Speed Limit Function
If the external speed limit function is selected in Pn002, set the V-REF input signal and Pn300.
Type
Input
Inputs an analog voltage reference as the servomotor speed limit value during force control.

Parameter
Uses the value set in Pn480 as the speed limit (internal
n. 0
speed limit function).
Uses V-REF (CN1-5, 6) as an external speed limit
input. Applies a speed limit using the input voltage of
n. 1
V-REF and the setting in Pn300 (external speed limit
function).

Setting Range
0 to 10000
The setting in this parameter is enabled when Pn002.1 is set to 0.

the servomotor used.
Parameter
Use the smaller value between maximum motor move-
n. 0 ment number and the value of Pn480 as speed limit
value.
Use the smaller value between excessive speed detec-
n. 1
tion speed and the value of Pn480 as speed limit value.
