www.controltechniques.com Issue: 2
4.6.2 Power down sequence
Unidrive SPM power and control modules must be powered down before the SPM
Power Selector Module.
4.6.3 Mode Select
When changing between operation modes (Master 1, Master 2) ensure that the
Power and control modules along with the SPM Power Selector Modules are powered
down during mode change.
4.7 SPM Power Selector Module configurations
SPM Power Selector Modules can be used in different configurations depending on the
application. Examples of possible configurations are listed below.
The following should be noted prior to design and/or choosing a particular configuration.
Unidrive SPM power and control modules along with the SPM Power Selector Module
must be powered down when changing operating modes.
NOTE
A maximum of 10 SPM Power Modules may be paralleled. The combined length of all
paralleling cables between the power modules and the SPM Power Selector Modules,
must be no more than 20m in total. A 1m paralleling cable is supplied with the SPM
Power Selector Module and a 2m paralleling cable is supplied with an SM Control Slave
module.
NOTE
For the SPM Power Selector to function correctly, the paralleling cables should be
connected to the appropriate ports on the SPM Power Selector as shown in the block
diagrams under each configuration.
NOTE
When installing paralleling cables between the SPM modules, the information given in
section 4.3.1
Connecting the Parallel cables to SPM modules on page 15 should be
adhered to.
