Input Signal - Mitsubishi Electric MR-J5 Series User Manual

■ALMWNG (Malfunction/Warning)
When an alarm occurs, ALMWNG turns off.
When a warning occurs (except for [AL. 09F Battery warning]), ALMWNG turns on and off repeatedly approximately every 1 s.
When neither an alarm nor a warning is occurring, ALMWNG will turn on in 2.5 s to 3.5 s after power-on.
■BW9F (AL9F warning)
When [AL. 9F Battery warning] occurs, BW9F turns on.
In the absolute position detection system with a battery-less ABS encoder, BW9F is always off.

Input signal explanation [A]
■TLA (Analog torque limit)
When TLA is enabled, all the torque generated by the servo motor is limited. Apply 0 V DC to +10 V DC between TLA and LG.
Connect the positive terminal of the power supply to TLA. The maximum torque is generated at +10 V. Refer to the following
for details.
MR-J5 User's Manual (Function)
If a value equal to or larger than the maximum torque is input to TLA, the value is clamped at the maximum torque.
Resolution: 12 bits
■TC (Analog torque command)
This is used to control all the torque generated by the servo motor. Apply 0 V DC to ±8 V DC between TC and LG. The
maximum torque is generated at ±8 V. Refer to the following for details. The torque at ±8 V can be changed with [Pr. PC13].
MR-J5 User's Manual (Function)
If a value equal to or larger than the maximum torque is input to TC, the value is clamped at the maximum torque.
■VC (Analog speed command)
Apply 0 V DC to ±10 V DC between VC and LG. At ±10 V, the servo motor speed is the value set in [Pr. PC12]. Refer to the
following for details.
MR-J5 User's Manual (Function)
If a value equal to or larger than the maximum speed is input to VC, the value is clamped at the maximum speed. When
changing the speed to the permissible speed, change the setting value in [Pr. PA 28.4].
Resolution: 14 bits or its equivalent (MR-J5-_A_-RJ: 16 bits or its equivalent)
For the MR-J5-_A_-RJ servo amplifiers, setting [Pr. PC60.1] to "2" changes the analog input resolution to 14 bits.
