Relation between servo parameters and objects

[Pr. PA11] and [Pr. PA12] are used for [Positive torque limit value (Obj. 60E0h)] and [Negative torque limit value (Obj. 60E1h)].

For [Pr. PA14 Travel direction selection] and [Pr. PC29.3 Torque POL reflection selection], the relationship between objects

and servo parameters that limit the torque changes as follows.

Setting value

[Pr. PC29.3]

Setting value of [Pr. PC78.1]

0: [Pr. PE53] Disabled

1: [Pr. PE53] Enabled

Checking "Limiting torque" status

TLC (Limiting torque) and Bit 13 (S_TLC) of [Status DO1 (Obj. 2D10h)] turn on when the servo motor torque reaches the

torque that was limited by the forward rotation torque limit and the reverse rotation torque limit.

4 APPLICABLE FUNCTIONS

4.9 Torque limit [G]

[Pr. PA11 Forward rotation torque

[Positive torque limit value (Obj. 60E0h)]
