Section 3 — Controlling and Monitoring the ATV58 Drive Controller Bulletin No. VVDED397053US

Drivecom Standard Adapted to the ATV58 Drive Controller November 2000

DRIVECOM STANDARD ADAPTED TO THE ATV58 DRIVE CONTROLLER

The ATV58 control process using the communication options conforms to

the DRIVECOM standard state chart. The DRIVECOM standard state

chart, the DRIVECOM standard, and the bypass for the DRIVECOM

standard are explained in the ATV58 Register Access Guide for

Communication Networks, VVDED397058US.

Communication Fault Detection

Setting CMI (word W402) bit 14 to 1 disables communication loss

detection. As a result, loss of communication does not cause the drive

controller to generate a fault. The drive controller continues its present

operation. Alternate control paths must be provided for starting, stopping,

and controlling the motor. No control commands are received during loss

of communication.

Controlling the Drive Controller—State Machine

The following Word designations can be used to initiate communication

to verify proper connection.

“Controlword” : 6040h

“Statusword” : 6041h

Enabling Periodic Data

“ProcDatEnab” : 6002h

The assignment of periodic data to the drive controller is enabled by the

default factory setting. Setting 6002h to 1 enables the periodic data.

Setting 6002h to 0 disables the periodic data.

LOSS OF CONTROL

Provide alternate control paths (Start, Stop, and Speed):

• When disabling communication loss detection.

• When motor control is required while a communication fault exists.

Failure to follow this instruction can result in death, serious

injury, or equipment damage.
