The voltage value relates to the value in parameter LOAD LIM (PQRS
19).
The value in function parameter FUNCT2 (A06) must contain < 512 >!
Parameter PQ-FUNCT (PQRS 16) has no significance in this case!
The analogue output M now indicates how near the load approaches a
machining-dependent torque limit. Four machining-dependent torque
thresholds can be set by the fourfold LOAD LIM parmeters.
The torque value indicated is calculated from the DC bus power and the
present motor speed.
