S210: provide actual torque to the S7

Hello all,

Today i want to present you two possibilities how to provide the actual torque value from the S210 drive to the PLC.

1. Acyclic communication with SINA_PARA(_S)

The actual torque value is read out acyclically with the communication block "SINA_PARA(_S)" via DS47.

You can either read out the parameter r0031 (actual torque value smoothed) or r0080 (actual torque value). We recommend using the unsmoothed actual torque value (r0080), because the S210 drive is a very dynamic drive in which you can expect to see rapid torque changes.

You can find additional information on the SINA_PARA(_S) in the following SIOS article:

2. Torque display through telegram 750

When using a technology object, we recommend working with the"PositioningAxis_1".StatusTorqueData.ActualTorquevariable. First the supplementary telegram 750 is set in the HW configuration. Then the technology object is still permitted to take into account the torque data as additional data. This must be enabled in the TO configuration under "Data exchanged with the drive -> Additional data" with the check mark "Torque data".

Hello,

The variable PositioningAxis_1".StatusTorqueData.ActualTorque is only available with technology objects on an S7 1500 PLC.

Hi,v

Please, can you tell me if it's the same procedure for a V90. Because I have done what you said but it doesn't work.

When I've added the telegram, the bit "EnableTorqueData" turned ON but the value of ActualTorque doesn't change. It stays at 0.0 (look at the attachment)

Is there something to do in V-Assistant to tell the V90 that we use the additionnal telegram 750 or it is automatic ? I've not found anything in V-Assistant to do that.

Thank you for your help

 Hello,

the V90 doesn't support the Telegram 750 .

Regards
