When LSP or LSN turns 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].
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
automatically depending on operation status. Refer to each timing chart in
section 6.2 and section 6.4.5.
CN1-16 Point table method/program method
Turning on MD0 will be automatic operation mode, off will be manual
operation mode. Changing an operation mode during operation will clear
the command remaining distance and the motor will decelerate to stop.
MD1 cannot be used.
Indexer method
Select an operation mode with combinations of MD0 and MD1. Refer to the
following table for combinations.
Changing an operation mode during operation will clear the command
remaining distance and the motor will decelerate to stop.
