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.  

 

 

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
