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 (
or
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
