Parameter description
5: Pulse given (DI5)
Frequency setting is given by the terminal pulse. Pulse reference signal specification: voltage range
9V ~ 30V, frequency range 0kHz ~ 100kHz. Pulse reference can only be entered from the input terminal
DI5 multifunction.
Relations DI5 terminal input pulse frequency corresponding to the set, and set by P4-28 ~ P4-31. The
correspondence between the two points is a straight line corresponding relationship. Pulse input
corresponding set is 100.0%, which means the percentage of relative maximum frequency P0-10.
6: Multi-stage instruction
When selecting the multi-instruction execution mode, You need to enter the DI terminals via digital
composition different states corresponding to different frequencies of the set value. VFD can set up more
than four segments command terminal, 16 states four terminals, PC function code can be corresponding to
any of 16 "multi-directive". Multi-directive" is the relative percentage of the maximum frequency P0-10.
DI digital input terminal as a multi-function terminal block command, you need to set the
corresponding group P4. For details, please refer to the relevant function parameter of group P4.
7: Simple PLC
When the frequency source is simple PLC, Running frequency of the inverter can be switched to run
between 1 to 16 arbitrary frequency command. Retention time of 1 to 16 frequency command and the
respective acceleration and deceleration time can be set by the user. For detailed contents refers to relative
instructions of PC group.
8: PID
Selection process PID control output is used as the operating frequency. Generally used for on-site
closed-loop control process, Such as closed-loop control of constant pressure, constant tension closed-loop
control applications and other conditions.
When applying PID as the frequency source, You need to set the PA group "PID function"
parameters.
9: Communication given
Refers to the main frequency source is the host computer via the communication mode.
VFD supports two kinds of communication: Modbus. CANlink, These two kinds of communication
can not be used.
Communication card must be installed when using communication, VFD two kinds of
communication cards are optional, Users need to choose according to their own requirements, And you
need to set the correct parameters for P0-28 "communication expansion card type."
