Parameterization
Machine data
● MD37010 $MA_FIXED_STOP_TORQUE_DEF (default for fixed stop clamping torque)
The value specified in the machine data is effective after activating the function, as long as
no explicit value is programmed using FXST.
● MD36042 $MA_FOC_STANDSTILL_DELAY_TIME (delay time standstill monitoring for
active torque/force limiting)
Permanent activation (FOCON/FOCOF)
Permanent activation of the "Force Control" function after POWER ON or RESET can be set
using the machine data:
MD37080 $MA_FOC_ACTIVATION_MODE, bit 0 and bit 1 (basic setting of the modal force/
torque limiting)
Bit
0
1
If a limiting torque or force is programmed using FXST = <value> before activation, then this
is effective from activation onwards.
If a limiting torque or force was not programmed using FXST = <value> before activation,
then the value specified in the machine data is effective as standard.
MD37010 $MA_FIXED_STOP_TORQUE_DEF (default for fixed stop clamping torque)
110
Meaning
Activate torque/force limiting
Deactivate torque/force limiting
Activate non-modal torque/force limiting
Channel axis name, type: AXIS
Value Meaning
0 The "Force Control" function is not active after POWER ON.
1 The "Force Control" function is active after POWER ON.
0 The "Force Control" function is not active after RESET.
1 The "Force Control" function is active after RESET.
Comment
; Modal activation of the torque limit
; X travels with reduced torque (15%)
; Changing the torque to 75%,
; Disable torque limit
