◆PWM signal can be used to control the operating frequency with terminals 7 and 8.
・No.7: Frequency setting signal changeover input terminal (SW4)
(OFF: PWM signal, ON: Controlled with signal set in parameter P004)
・No.8: PWM signal input terminal
Note 1) When using PWM signal to control output
frequency, P087 to P089 must be set.
Note 2) Use a PWM signal transistor (Tr) that has
the following capabilities:
・Max. rated voltage: 50VDC or more
・Rated current: 50mA or more

D+ : Transmission line + terminal
(RS485 communication)
D-
: Transmission line - terminal
(RS485 communication)
E
: Terminator terminal
(RS485 communication)
* Connect the D+ side and D+ side, D- side
and D- side of the communication terminals.
* The D- side and E side of the inverter to be
a terminator should be shorted. Do not short
the units other than the terminator.
◆Terminals to connect personal computers and PLCs by the RS485 communication.
