VLA (Analog speed limit)
Apply 0 V DC to ±10 V DC between VLA and LG. At ±10 V, the servo motor speed is the value set in [Pr. PC12].
For details, refer to "Speed limit" in the following manual.
MR-J5 User's Manual (Function)
If a value equal to or larger than the maximum speed is input to VLA, the value is clamped at the maximum speed. When
changing the speed to the permissible speed, change the setting value in [Pr. PA28.4].
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.
PP/NP/PP2/NP2/PG/NG (Forward/reverse rotation pulse train)
This is used to enter a command pulse train.
• For open-collector type (sink input interface)
The maximum input frequency is 200 kpulses/s. For A-phase and B-phase pulse trains, 200 kpulses/s will be the frequency
after multiplication by four.
Input the forward rotation pulse train between PP and DOCOM.
Input the reverse rotation pulse train between NP and DOCOM.
• For open-collector type (source input interface)
The maximum input frequency is 200 kpulses/s. For A-phase and B-phase pulse trains, 200 kpulses/s will be the frequency
after multiplication by four.
Input the forward rotation pulse train between PP2 and PG.
Input the reverse rotation pulse train between NP2 and NG.
• For differential receiver type
The maximum input frequency is 4 Mpulses/s. For A-phase and B-phase pulse trains, 4 Mpulses/s will be the frequency after
multiplication by four.
Input the forward rotation pulse train between PG and PP.
Input the reverse rotation pulse train between NG and NP.
The command input pulse train form, pulse train logic, and command input pulse train filter are changed in [Pr. PA13]. When
the command pulse train exceeds 1 Mpulse/s and is 4 Mpulses/s or less, set [Pr. PA13.2] to "0".
For details, refer to "Position control mode (P)" in the following manual.
