Digital inputs (FWD, REV, MI1~MI8, COM)
When using contacts or switches to control the digital inputs, please use high quality
components to avoid contact bounce.
Transistor outputs (MO1, MO2, MCM)
Make sure to connect the digital outputs to the right polarity.
When connecting a relay to the digital outputs, connect a surge absorber across the coil and
check the polarity.
PG Function Explanation
1. When C200 is running at speed mode, it uses external terminal MI7~MI8 as PG connection
function terminal.
2. C200 uses encoder, open collector of only 24Vdc. The maximum cable length of encoder is 30m.
For example: Delta's encoder (ES3-06CN6941).
3. For External terminal MI7~MI8, their the minimum working voltage is 21Vdc, maximum
input/output frequency is 33kHz. Refer to the formula below:
Maximum output rotation speed (rpm)=(120*frequency/motor pole number)
For example: Set up PG function to be 600pulse, pole number to be 4 and the maximum rotation
frequency is 60Hz.
The maximum rotation speed(rpm)=( 120*60)/4=1800rpm
1800/60*600=18000Hz
4. Set up Pr10-01~ 10-04 before using PG function. Its wiring diagram is shown as below:
