Note
Analog torque limit for S200PTI
F
or S200PTI, when the signal TLM1-TLM0 status is 0-1, p29050[1] is invalid and the analog
voltage from the analog input 1 is used as the torque limit.
The analog voltage from the analog input 1 corresponds to an internal percentage value. Default
torque value is the rated motor torque (r0312). The analog voltage of 10 V corresponds to the
rated motor torque.
The following diagram shows how the internal torque limit functions. When the torque
setpoint reaches the t
orque limit, the actual torque output is limited to the value selected by
TLIM0/TLIM1.

Overall torque limit
The overall tor
que limit takes e󹪜ect when a quick stop (OFF3) happens. In this case, the servo
drive brakes with a maximum torque.
Table 9-23 Parameter - overall torque limit
Parameter Value range Default Unit Description
p1520 -1000000.00 ... 20000000.00 0 Nm Overall torque limit (upper)
p1521 -20000000.00 ... 1000000.00 0 Nm Overall torque limit (lower)
Torque limit reached (TLR)
When the generated t
orque has nearly (internal hysteresis) reached the value of the upper
torque limit, lower torque limit or analog torque limit, the signal TLR is output.
