When LSP or LSN is turned off, [AL. 99 Stroke limit warning] occurs, and
WNG (Warning) turns on. When using WNG, enable it by setting [Pr.
PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47].
However, [Pr. PD47] is not available with MR-J4-03A6-RJ servo amplifiers.
Turning off TL will enable [Pr. PA11 Forward torque limit] and [Pr. PA12
Reverse torque limit], and turning on it will enable TLA (Analog torque
limit). For details, refer to section 3.6.1 (5) of "MR-J4-_A_(-RJ) Servo
Amplifier Instruction Manual".
For the indexer method, [Pr. PC35 Internal torque limit 2] will be enabled
automatically depending on operation status. Refer to each timing chart in
section 6.2 and section 6.4.5.
To select [Pr. PC35 Internal torque limit 2/internal thrust limit 2], enable
TL1 with [Pr. PD04], [Pr. PD06], [Pr. PD08], [Pr. PD10], [Pr. PD12], [Pr.
PD14], [Pr. PD18], [Pr. PD20], [Pr. PD22], [Pr. PD44], and [Pr. PD46]. For
details, refer to section 3.6.1 (5) of "MR-J4-_A_(-RJ) Servo Amplifier
Instruction Manual".
For the indexer method, [Pr. PC35 Internal torque limit 2] will be enabled
