STATUS
• The Servo does not perform position control and speed control, but directly
performs torque control.
• Can be used during phases 2 and 3.
• A command warning will occur and the command will be ignored in the fol-
lowing cases.
- During phases other than phases 2 and 3:
MECHATROLINK-II command warning (A.95)
- If the SERVOPACK is Servo OFF: MECHATROLINK-II command warning
(A.95)
• OPTION can be selected. Refer to
4.5.2 Option Field Specifications:
OPTION
for details.
• TOREF (torque reference)
The unit for torque reference is [maximum motor torque/40000000H]. The
direction is specified by the sign.
When the designation for TOREF is larger than the maximum motor torque, it
is clamped at the maximum torque.
• STATUS (status)
D11: V_LIM (speed limit bit)
0: Speed limit not detected
1: Speed limit detected
• MONITOR1, 2, 3, 4 (monitor)
The unit for torque is [maximum motor torque/40000000H].
• Setting the speed reference option (VLIM)
Setting range: 0 to 40000000H (maximum motor speed/40000000H)
