3 OPTION 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
following cases.
- During phases other than phases 2 and 3: Command warning 1 (A.95A)
• OPTION field can be used. Refer to 6.5.2 Option Field Specifications:
OPTION for details.
• TOREF
TOREF is a torque reference and has signed 4 bytes of data. The unit for
torque reference is [maximum motor torque/40000000H]. The direction is
specified by the sign.
When the designation for TOREF is larger, it is clamped at the maximum
torque.
• During execution of this command, the following bits of STATUS are
allocated.
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)
