Wiring For Pwm/Pulse Input Controlled Operating Frequency Mode (Terminal No.7, 8); Wiring For Open-Collector Output Terminals (Terminal No.10 To 12) - Panasonic VF200 Instruction Manual

■ Wiring for PWM/Pulse input controlled Operating Frequency Mode (Terminal No.7, 8)

·When parameter P087 is set to "1", the operating frequency will be controlled
by external PWM signal from PLC, etc.
·When parameter P087 is set to "2", the operating frequency will be controlled
by external pulse signal from PLC, etc.
·Terminal No.7 is the input terminal for changeover of frequency setting signal
(SW4) (OFF: PWM/Pulse input signal, ON: controlled by the signal set in parameter P004),
while terminal No.8 is the input terminal for PWM/Pulse input signal .
·As for the transistor for PWM/Pulse input signal, please use one with maximum
voltage rating over 50 V and maximum current rating over 50 mA.
·In addition, to use PWM signal for operating frequency control, relevant
settings must be made to parameter P088 and P089.
·Use pulse signal for operating frequency control, relevant settings must be
made to parameter P174.
·When setting value is "1" or "2", the SW function for SW4(terminal No.7) and
SW5(terminal No.8) will be forced to be used for controlling PWM/pulse signal only.

■ Wiring for Open-collector Output Terminals (Terminal No.10 to 12)

·When using open-collector output terminals to drive inductive loads, always
connect a freewheel diode.
