• Input terminal for position command pulse. You can select by setting up
PULSH1
Pr40 (Selection of command pulse input) to 1.
• This input becomes invalid at such control mode as velocity control or
PULSH2
torque control, where no position command is required.
• Permissible max. input frequency is 2Mpps.
• You can select up to 6 command pulse input formats with Pr41 (Setup of
SIGNH1
command pulse rotational direction) and Pr42 (Setup of command pulse
input mode).
SIGNH2
For details, refer to the table below, "Command pulse input format".

• Input terminal for the position command. You can select by setting up Pr40
OPC1
(Selection of command pulse input) to 0.
• This input becomes invalid at such control mode as the velocity control or
PULS1
torque control, where no position command is required.
PULS2
• Permissible max. input frequency is 500kpps at line driver input and
200kpps at open collector input.
OPC2
• You can select up to 6 command pulse input formats with Pr41 (Setup of
command pulse rotational direction) and Pr42 (Setup of command pulse
SIGN1
input mode).
