ACS880 or ACSM1 or ACS580 with MODBUS RTU

Used drive Communication Module: FSCA-01:

Question: How many values should be exchanged?

• status word, actual value1 (speed), actual value2 (torque), control word, reference1 (speed) and reference value2 (torque)
  • communication profile in drive parameters: ABB Drives classic
  • communication Function Block in AC500 program: ACS_COM_MOD_RTU ACS_COM_MOD_RTU Communication for ACS / DCS Drives via MODBUS RTU
  • control Function Block in AC500 program: ACS_DRIVES_CTRL_STANDARD ACS_DRIVES_CTRL_STANDARD Control of ACS Drives with ABB-Drives Profile
  • scaling: ACS_REF_SCALING (optional) ACS_REF_SCALING Scaling for ACS / DCS Reference and Actual Values
• status word, actual value1 (speed), actual value2 (torque), control word, reference1 (speed), reference value2 (torque) and up to 12 more values read from drive and up to 12 more values write to the drive
  • communication profile in drive parameters: ABB Drives enhanced
  • communication Function Block in AC500 program: ACS_COM_MOD_RTU_ENHANCED ACS_COM_MOD_RTU_ENHANCED Communication for ACS Drives via MODBUS RTU using ABB Drives Profile Enhanced
  • control Function Block in AC500 program: ACS_DRIVES_CTRL_STANDARD ACS_DRIVES_CTRL_STANDARD Control of ACS Drives with ABB-Drives Profile
  • scaling: ACS_REF_SCALING (optional) ACS_REF_SCALING Scaling for ACS / DCS Reference and Actual Values
• to exchange more than above mentioned values use additionally the following blocks:
  • ACS_MOD_READ_N_PRM ACS_MOD_READ_N_PRM Read N Parameters from an ACS Drive via MODBUS RTU
  • ACS_MOD_WRITE_N_PRM ACS_MOD_WRITE_N_PRM Write N Parameters to an ACS/DCS Drive via MODBUS RTU
