Communcation Parameters The following communication paramters are relevant in case of external drives control. Cmd Location (2.02) Purpose: Determines whether Drive is externally controlled via conventional I/O or serial interface. Value: 0 Macro depend 1 Terminals (X1...X5 on SDCS-CON-3) 2 Bus - The serial interface for external control is specified in Parameter Modul Type (8.01) (Fieldbus, RS232-Port or Panel-Port) 3 Key - Automatic switch over between bus and terminals Comm Fault Time (2.08) Purpose: For supervision of communication on the serial interface which is used for external drive control (defined in Paramter Modul Type (8.01). Value: 0.01...10 sec Determines the maximum allowed down time for communication in seconds. If no messages are received within this time, an error message will be issued and the drive will behave according to Parameter Comm Fault Mode (2.07); 0.00s = ignore error, Continue drive operation. Comm Fault Mode (2.07) Purpose: Defines how the drive will behave in case of communication error. Value: 0 Brake with deceleration ramp (Parameter 5.10), then switch off drive and error message 1 Brake with torque = torque limit (Parameter 3.07, 3.08), then switch off of drive and error message. 2 Immediate switch off drive and error message Telegram Structure The serial communication with a PLC can be carried out via a field bus adapter, a RS232 port or a panel port. Irrespective of the bus protocol, these ports communicate with the DCS400 software via specified data sets. Four data sets are available with three 16- bit words each. The data sets have the following significance: Control and reference transmission, from the PLC to the drive Data set 1.1: Main Ctrl Word (5 bits set by parameter group 9) Data set 1.2: Bus Main Ref Data set 1.3: Bus Aux Ref Status information and actual value transmission, from the drive to the PLC Data set 2.1: Main Status Word (4 bits set by parameter MSW bit 1x Ass (6.22…6.25)) Data set 2.2: Actual value 1 (set by param. Dataset 2.2 As (6.20)) Data set 2.3: Actual value 2 (set by param. Dataset 2.3 As (6.21)) Digital and analogue value transmission, from the PLC to the drive Data set 3.1: DO1...DO5 (set by 6.11...6.15) Data set 3.2: AOx, Scaling: ±4096 ^ = ±10V (set by 6.05/6.08) Data set 3.3: AOx, Scaling: ±4096 ^ = ±10V (set by 6.05/6.08) Actual value transmission, from the drive to the PLC Data set 4.1: Fld Cur Act (fixed) Data set 4.2: Power Act (fixed) Data set 4.3: Torque Act (fixed)
