5.5 Commissioning with control signal terminals (default settings)
DC1-S… variable frequency drives come pre-configured for their rated mains
voltage and motor output. Once the corresponding motor and mains voltage
are connected, these drives allow for direct operation via their control signal
terminals.
Simplified connecting example
The potentiometer should have a fixed resistance (connection to the control
terminals 5 and 7) of at least 1 k
Ω and up to a maximum of 10 k Ω .
A standard fixed resistance of 4.7 k Ω is recommended.
When the specified supply voltage is applied at the mains connection
terminals (L1/L, L2/N), the switched-mode power supply unit (SMPS) in the
internal DC link will be used to generate the control voltage and light up the
7-segment LED display (
StoP
). At this point, the variable frequency drive will
be ready for operation (correct operating status) and in Stop mode.
The start enable signal is sent by applying the +24 V voltage on terminal 1:
FWD = Start.
