4.4 Commissioning with local controls
The variable frequency drives of the DC1-...-A6S... series with local controls
are factory-set and internally wired. They can be started directly using the
local controls when the rated motor output for the mains voltage is
connected.
When the specified supply voltage is applied at the mains connection
terminals (L1/L, L2/N, L3) and the main switch on the mains side is switched
on, the switched-mode power supply unit (SMPS) in the DC link will be used
to generate the control voltage and the 7-segment LED display will light up
(StoP). At this point, the variable frequency drive will be ready for operation
(correct operating status) and in Stop mode. The start enable signal can then
be issued by selecting a rotating field direction:
• FWD = Clockwise rotating field (Forward Run)
• REV = Counterclockwise rotating field (Reverse Run)
At this point, the output frequency (0 - 50 Hz), and the speed of the
connected three-phase motor (0 - n
Motor
) as a result, can be adjusted by
using the internal setpoint potentiometer. Output frequency changes will be
delayed based on the specified acceleration and deceleration times.
When
using the device’s default settings, these times will be set to 5 seconds.
￫
Make sure that the switches are open before switching on the
mains voltage.
