~
(4) Speed limit in torque control mode
(a) Speed lunit value and speed
The speed is limited to the hit value set in parameter No. 8 (internal speed limit 1) or the value set
in the applied voltage of the analog speed hit (VLA). A relationshp between the analog speed hit
(VLA) applied voltage and the servo motor speed is as in (a), (3) in section 3.4.3.
Generally, make connection as shown below:
.____ Servo amplifier
Japan Resistor
RRSlO or equivalent
When a precision speed command is required, refer to (a), (3) in section 3.4.3.
@I) Speed selection 1 (SP1) and speed limit value
Use speed selection 1 (SP1) to select between the speed set by the internal speed command 1 and
the meed set by the analog speed bit (VLA) as indicated in the following table:
(Note) External Input Signals
ED1
Speed Command Value
0 I Analog speed limit (VIA)
1 I Internal speed limit 1 (parameter No. 8)
Note.0: SP1-SG off (open)
1: SP1-SG on (short)
When the internal speed lunit 1 is used to command the speed, the speed does not vary with the
ambient temperature.
(c) Limiting speed (VLC)
As in (c), (3) in section 3.4.3.
(5) Toque control in torque control mode
As in Section 3.4.3 (1).
(6) Torque limit in torque control mode
As in Section 3.4.3 (2).
