24 Control circuit for NR_2N Dahlander starter
NR-2N Dahlander STARTER (M102 Only)
NR-2N Dahlander uses three contactors to control
motor rotation speed where motor is equipped
with a three-phase winding. Rotation speed can
be changed “on the fly” without stop command in
between. Low speed (start 1) can be changed to
high speed (start 2) immediately, and high speed
can be changed to low speed after a changeover
time.
Current measurement for NR-2N Dahlander uses
two external current transformers measuring
current from motor main supply. External current
transformers can be selected separately for both
speeds.
Operating sequence in NR-2N Dahlander
•Sending command Start1 (low speed N1) to
close contactor CCA
• Sending command Start2 (high speed N2) to
close contactor CCB
• Contactors are latched
• Stop command opens CCA or CCB
* The assigned DI and PIN code may change in actual design
The following control sequence are supported:
• Stop → Start1 → Stop
• Stop → Start2 → Stop
• Stop → Start1 → Start2 → Stop
• Stop → Start2 → Changeover delay → Start1 →
