ABB HIES207036R003 control module

Description

The position difference for electrical shaft control is set to zero (0) in three ways:

(1) as in earlier releases with parameter set no. 1 is changed to parameter set no. 2 as well as

with parameter set no. 3 is changed to parameter set no. 4. Both these cases are executed by

changing DI no. 1 from 0 to 1.

(2) when the combination of Control signals A NOR B changes to Boolean True. Example:

Running in Sub mode MF2 until the operator or other external conditions decides to switch to

electrical shaft (Sub MF1) is done without stopping by simply changing control signal B

from 1 to 0. Control A is all the time 0.

(3) From 10_05: with parameter 05.20, USE_DI16 is set to 2 for a Follower that has Cabin I/O, the

function Brake #4 acknowledged for DI 16 is changed external reset of the Electrical shaft.

The sub mode MF3 is especially suitable for load sharing in four ropes grab systems. It can also be used for load

sharing for Travel motions, although not needed for most EOT cranes.

The sub mode MF4 is useful in some applications. It can as example make two motions with analogue tachome

ters to move with the (for the eye) same speeds.

4.20.2.1. Control signals A and B

The signals A and B are controlled in following way:

Control signal A:

Closed contact of terminal Master ASTAT DATX 110: -X9:5-6. -X9:5 is +110 V DC.

Control signal B:

Closed contact of terminal Follower ASTAT DATX 110: -X9:5-6. -X9:5 is +110 V DC.

4.20.3. Current follower

ASTAT can as a single controller work with two parallel bridges, with a total capacity of maximally 2200 A. In some

installations this capacity is not enough. Of that reason a follower mode that doubles the capacity is developed. Set

up: Master has 20.01 = 1, Current Follower has 20.01 = 3.

Connection:

Each Motion controller of maximally 2200 A is conventionally connected to motor and network. Nothing prevents

that a 12-pulse connection is used, although there are normally no big advantages with 12-pulse.

Supervision of parallel bridges, there can be two parallel bridges of the totally four bridges used in the full system,

must have both open contacts connected in parallel to the DI no. 17 of the Masters DATX 110. As usual, these

contacts should be open for a healthy system.

All control signals should be connected to the Masters DATX 110 and Cabin I/O. The system allows that the Fol

lowers DATX 110 is removed, but it is mostly kept for separate Motion control.

Optical M/F fiber cable installed.

Settings:

Parameter 11.39 should be changed from 20 to 30 ms (and more if slow opening rotor contactors are used; add

always 10 ms to the actual opening time).
