Control and Monitoring of the Altivar 28
The Altivar 28 speed controller can communicate using the integrated RS485 serial link, with the connection kit (order separately).
This document defines the variable speed controller control process using the serial link as well as the internal variables for the speed controller.
The Altivar 28 user’s manual should be consulted in order to obtain more detailed explanation (operation,
"factory" settings, etc).
The Altivar 28 control process using the serial link conforms to the DRIVECOM standard state chart. The chart below has been adapted to the characteristics of the Altivar 28 to simplify programming. Each state represents an aspect of the internal behaviour of the speed controller.
The speed controller status can be modified by sending a control word (CMD) or by the occurrence of an event (example : lock following malfunction). The speed controller status is given by the value of the status register (ETA).

Control and Monitoring of the Altivar 28
Stop requests which can be activated by the terminal always have priority:
Type of stop
Freewheel stop
Fast stop
DC injection stop
3-wire control stop via logic input STOP (LI1)
Corresponding DRIVECOM state
"ATV28 powered up"
"ATV28 running"
"ATV28 running"
"ATV28 powered up"
Actions for restoring control of the Altivar 28 using the serial link
- set the logic input assigned to the "Freewheel stop" function to 1 (active at 0)
- perform the transitions required to return the speed controller to “run” status.
- set the logic input assigned to the "Fast stop" function to 1 (active at 0)
- set the logic input assigned to the "DC injection braking" function to 0 (active at 1)
- set the logic input assigned to the STOP function to 1
(active at 0)
- perform the transitions required to return the speed controller to “run” status.
Forced to local
If a logic input assigned to the forced to local function is set to 1, the commands present at the terminals are taken into account.
In forced to local mode all write requests from the fieldbus are refused.
Warning: when forced to local mode ceases, line control is restored at the point which was active at the moment of interrupt caused by forced to local.
Communication bus monitoring
Bit 14 (NTO) of control word CMI is used to inhibit communication monitoring.
If NTO = 1, the speed controller no longer takes into account communication errors from the communication bus controlling the speed controller.
For safety reasons its use must be restricted to the debug phase.
Warning
Only those addresses and values defined in this document may be used. All other addresses and values should be considered as reserved and should not be written. If this precaution is not respected it may result in malfunctions.

(if AIC / AI2 = PII)
(1) Each action of bits 0, 1, and 2 of W402 is only accepted if the motor is stopped and the speed controller powered up without a USF fault. When accepted, it interrupts communication while it executes, or for 2 seconds max.
The PLC "time out" must therefore be set to a higher value in order to avoid tripping.
During this time the speed controller display indicates :
•
I n
•
N E t to return to factory settings and to return to EEPROM parameters (bits 0 and 2) to memorize write operations in EEPROM (bit 1).
If several of these bits are activated simultaneously, the following priorities are respected :
• bit 0 has priority over bits 1 and 2
• bit 1 has priority over bit 2

Special "DRIVECOM" parameters
(read and write)
Use of parameters W603 to W615 necessitates a special configuration of parameter SdS (W41) in drive parameter menu drC- :
SdS = 60/p where p = number of pairs of poles in motor.
Example : motor 1450 Rpm (revolutions per minute) at 50Hz : 4-pole motor, so SdS = 30.
This parameter enables the speed controller to establish the relationship between the frequency in Hz and the speed in Rpm.
