Fieldbus control through a fieldbus adapter 437 Contents of the fieldbus Control wordThe upper case boldface text refers to the states shown in the state diagram onpage 439.Bit Name Value State/Description0 Off1 control 1 Proceed to READY TO OPERATE.0 Stop along currently active deceleration ramp. Proceed toOFF1 ACTIVE; proceed to READY TO SWITCH ON unlessother interlocks (OFF2, OFF3) are active.1 Off2 control 1 Continue operation (OFF2 inactive).0 Emergency OFF, coast to a stop.Proceed to OFF2 ACTIVE, proceed to SWITCH-ONINHIBITED.2 Off3 control 1 Continue operation (OFF3 inactive).0 Emergency stop, stop within time defined by driveparameter. Proceed to OFF3 ACTIVE; proceed to SWITCH-ON INHIBITED.WARNING: Ensure motor and driven machine can bestopped using this stop mode.3 Run 1 Proceed to OPERATION ENABLED.Note: Run enable signal must be active; see drivedocumentation. If the drive is set to receive the Run enablesignal from the fieldbus, this bit activates the signal.0 Inhibit operation. Proceed to OPERATION INHIBITED.4 Ramp out zero 1 Normal operation. Proceed to RAMP FUNCTIONGENERATOR: OUTPUT ENABLED.0 Force Ramp function generator output to zero. The drive willimmediately decelerate to zero speed (observing the torquelimits).5 Ramp hold 1 Enable ramp function.Proceed to RAMP FUNCTION GENERATOR:ACCELERATOR ENABLED.0 Halt ramping (Ramp Function Generator output held).6 Ramp in zero 1 Normal operation. Proceed to OPERATING.Note: This bit is effective only if the fieldbus interface is setas the source for this signal by drive parameters.0 Force Ramp function generator input to zero.7 Reset 0=>1 Fault reset if an active fault exists. Proceed to SWITCH-ONINHIBITED.Note: This bit is effective only if the fieldbus interface is setas the source of the reset signal by drive parameters.0 Continue normal operation.8 Inching 1 1 Accelerate to inching (jogging) setpoint 1.Notes:• Bits 4…6 must be 0.• See also section Jogging on page 65.0 Inching (jogging) 1 disabled.9 Inching 2 1 Accelerate to inching (jogging) setpoint 2.See notes at bit 8.0 Inching (jogging) 2 disabled.10 Remote cmd 1 Fieldbus control enabled.0 Control word and reference not getting through to the drive,except for bits 0…2.
