Operation
 Internal Speed Limit Function
If the internal speed limit function is selected in Pn002.1, set the limit of the maximum speed of the servomo-
tor in Pn480. The limit of the speed in Pn408.1 can be either the maximum speed of the servomotor or the
overspeed alarm detection speed. Select
the overspeed alarm detection speed to limit the speed to the maxi-
mum speed of the servomotor or the equivalent.
Note: The servomotor’s maximum speed or the overspeed alarm detection speed will be used when the setting in this
parameter exceeds the maximum speed of the servomotor used.
 External Speed Limit Function
If the external speed limit function is selected in Pn002.1, set the V-REF input signal and Pn300.
Inputs an analog voltage reference as the servom
otor speed limit value during force control.
Notes:
• The smaller value of the speed limit input from the V-REF and the value of Pn480 is enabled when Pn002.1
is set
to 1.
• The setting in Pn300 determines the voltage level to b
e input as the limit value. Polarity has no effect.
• When Pn300 is set to 6.00 (factory setting) and 6 V is in
put to V-REF (CN1-5, 6), the speed is limited to the
rated speed of the servomotor used.
