5.3. Control connections
5.3.1. Connection procedure
•
remove the front panel that is secured with screws.
•
for control connections use cable of 0,5 mm
2
screened
•
connection cable should enter at the bottom.
•
connect screen to earth at the drive only .
•
connect control cable to terminals
(connections are shown in FIG 2).
•
refit the front panel
FIG 2
NOTE : always segregate control and power cabling !
5.3.2.
Specifications of control inputs and outputs
Complete isolation between control and power electronic circuits.
•
Logic inputs
- run/stop
: control switch or PLC output
- preset speeds selection : control switches or PLC outputs
(Three binary preset speed inputs select 8 preset speeds)
Input voltage : min : 15 V
DC
Input current : cca 8,5 mA (24 V
DC
)
nominal : 24 V
DC
max : 30 V
DC
Input signal delay : max 5 ms
•
Logic output
- drive status : volt-free change-over relay contact - 250 V
AC
;
8 A
6. Drive status indication
6.1. On the front panel of the drive
•
LED "POWER" (red): input voltage is present, all internal voltage levels are correct
•
LED "FAILURE" (red): internal or external trip (e.g. overvoltage
;
overcurrent
;
short-circuit ... )
the drive is stopped (disconnected from the load)
6.2. Remote indication
•
Volt-free change-over relay contact
Control terminals :
8
- normally open
7
- common
9
- normally closed
Relay energised when : drive healthy
Relay de - energised when : power off or drive tripped (disconnected from the load)
