Fieldbus control through a fieldbus adapter 433 Contents of the fieldbus Control wordThe upper case boldface text refers to the states shown in the state diagram (page436).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 D.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 D.0 Force Ramp function generator output to zero. The drive willimmediately decelerate to zero speed (observing the torque limits).5 Ramp hold 1 ramp function.Proceed to RAMP FUNCTION GENERATOR: ACCELERATOR D.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 118).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 d.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.
