0x2946 | 0x3146 - Cyclic sync torque mode: Speed limitation
0x6071 | 0x6871 - Torque demand
0x6072 | 0x6872 - Max torque
The torque control contains a speed limitation as a protective function against very high speeds. High speeds can
occur in the case of a mere torque selection if no counter-torque is available (load-free machine).
The speed limitation function takes effect if the actual motor speed reaches the limit values set here: The motor
speed is kept at the limit value in each case. If the machine is decelerated by a counter-torque again, the speed
limitation hands control back to the external setpoint via the setpoint torque.
Note!
The upper limit value must be set to a greater value than the lower limit value. There is no plausibility check in the
i700 servo inverter.

Symmetrical selection of the maximum permissible torque
•100% ≡ rated motor torque (0x6076
or 0x6876 for axis B)
• This parameter serves to implement a statically and bipolarly acting torque limitation. This can be used, for
instance, as overload protection of the mechanical transmission path/elements starting at the motor shaft.
• This limitation acts independently of the unipolarly acting torque limitations which act as process data on the
objects 0x60E0
(or 0x60E0 for axis B) and 0x60E1 (or 0x60E1 for axis B). For details see signal flow.
