Description of function
+10 Vdc power supply for frequency setting POT.
(POT: 1 to 5 kohm).
(1) The frequency is set according to the external
analog input voltage command.
• 0 to +10 Vdc / 0 to 100%
• Reversible operation using +/- signal: 0 to +/-10
Vdc / 0 to 100%
• Inverse mode operation: +10 to 0 Vdc / 0 to 100%
(2) The PID control feedback signal is input.
* Input resistance: 22 kOhm
(1) The frequency is set according to the analog
input current command.
• 4 to 20 mAdc / 0 to 100%
• Inverse mode operation: 20 to 4 mAdc / 0 to 100%
(2) The PID control feedback signal is input.
* Input resistance 250 ohm
Common for analog signals
Forward operation with FWD-P24 ON and
deceleration and stop with FWD-P24 OFF.
Reverse operation with REV-P24 ON and
deceleration-stop with REV-P24 OFF.
A coast-to-stop command from an external
device, external alarm, alarm reset, multi-step
frequency selection and other functions can be
assigned to the X1 through X5 terminals. Refer to
the terminal function E01 to 05 setting method in
section 5-2 Detail Description of Each Function.
