[Weirdest thing...]

Have you any comms going on?

[Time Stamp input change of state for Diagnostic]

Consider upgrading to FX3U and you can make use of the R Registers.

[CC-Link problem with PT100 module]

Check the Buffer Memory to see if the issue is with the network or the I/O Refresh.

[GX Works2 version 1.73]

Version 1.77F Now available.

[Torque Control for Winder in MR-J3-B Servo with QD75-MH2]

Appreciate that, it's 1 month from Launch in UK, (Due to Tsunami). I Don't know the current availability in India.

[D700 inverter communication through FX3U PLC]

Use the 485 ADP Module that fits on the Left Hand Side Bus.

[Torque Control for Winder in MR-J3-B Servo with QD75-MH2]

Neither the QD75MH or 20SSCH can do true Torque control with the MR-J3-B amplifier. (Only Torque Limit) For Torque control mode with MR-J3-B you need to use Motion CPU, Q172H, Q172D or Q170M. MR-J3-A amplifier supports Torque control. LD77MH4 and 16 will also support Torque control when it's available.

[Is it possible to perform positioning control by FR-A740-****-IN vfd via SSCNET III (FX3U-20SSC-H)?]

To be clear, A700 VSD with SSCNET III option cards can only be used on the Q Series Motion CPU. (Q172H, Q172D etc). In addition, an Encoder and Encoder feedback card must also be used.

[Mitsubishi MR-J2S-A]

Hi, Don't confuse the Servo Motor's encoder resolution with the 'Emulated' encoder output from the Amplifier. The MR-J2S range of Servo motors use an Absolute Serial Encoder with a resolution of 131072 ppr. The Amplifier has an output terminal to allow a pulse train to be fed out that corresponds to the encoder on the servo, however 131072 ppr is not possible. Using Parameter 27 you can configure a ppr of 1 to 65535. 4000 is the default.

[A172SHCPUN]

SC09 will get you comms. PCMCIA was SSCNET and SSCNET II adapter to allow faster comms and also diagnostics for High Speed monitoring and Motion Trend / Graph.
