3.3.4 Wiring Diagrams of I/O Signals (CN1)
The valid voltage range of analog input command in speed and torque mode is -10V ~+10V.
The command value can be set via relevant parameters.
C1: Speed / Torque analog signal input
There are two kinds of pulse inputs, Line driver input and Open-collector input. Max. input pulse
frequency of Line driver input is 500kpps and max. input pulse frequency of Open-collector input is
200kpps.
NOTE
1) In order to protect the internal circuit, when using open collector input, please
ensure to connect one 1 ~ 2 KΩ current limit resistor before Pin 19(/SIGN) and
Pin 21(/PULSE) respectively (Please refer to the wiring diagram on next page).
2) For the specifications of connected current limit resistor, please refer to the
