Fieldbus control through a fieldbus adapter 411 Contents of the fieldbus Control wordThe upper case boldface text refers to the states shown in the state diagram (page414).Bit Name Value STATE/Description0 Off1 control 1 Proceed to READY TO OPERATE.0 Stop along currently active deceleration ramp. Proceed to OFF1ACTIVE; proceed to READY TO SWITCH ON unless other 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-ON INHIBITED.2 Off3 control 1 Continue operation (OFF3 inactive).0 Emergency stop, stop within time defined by drive parameter.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 drive documentation. Ifthe drive is set to receive the Run enable signal from the fieldbus, thisbit activates the signal.0 Inhibit operation. Proceed to OPERATION INHIBITED.4 Ramp out zero 1 Normal operation. Proceed to RAMP FUNCTION GENERATOR:OUTPUT ENABLED.0 Force Ramp function generator output to zero. The drive willimmediately decelerate to zero speed (observing the torque limits).5 Ramp hold 1 Enable ramp function.Proceed to RAMP FUNCTION GENERATOR: ACCELERATORENABLED.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 set as thesource 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 set as thesource 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 Rush control (page 98).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, exceptfor bits 0…2.11 Ext ctrl loc 1 Select External Control Location EXT2. Effective if control location isparameterized to be selected from fieldbus.0 Select External Control Location EXT1. Effective if control location isparameterized to be selected from fieldbus.12 User bit 0 1 TBA0 TBA13 User bit 1 1 TBA0 TBA
