3-1-6 Control Input Details
No allocation: Zero Speed Designation (VZERO)
There is no default allocation. Zero Speed Designation Selection (Pn315) is set to 0 (disabled) by
default. The logic and allocation of input terminals (CN1 pin 1 to 8, 9, 26 to 33) can be changed using
Input Signal Selection 1 to 10 (Pn400 to Pn409).
 Function
The Zero Speed Designation Input (VZERO) enables to forcibly set the speed command value to 0.
It is enabled when Zero Speed Designation Selection (
Pn315) is set to 1 to 3.
No allocation: Speed Command Sign Input (VSIGN)
There is no default allocation. Speed Command Direction Selection (Pn301) is set to 0 (disabled) by
default. The logic and allocation of input terminals (CN1 pin 1 to 8, 9, 26 to 33) can be changed using
Input Signal Selection 1 to 10 (Pn400 to Pn409).
 Function
This input signal specifies the rotation direction for the speed command.
When Speed Command Direction Selection (
Pn301) is set to 1 (enabled), the rotation direction setting
for the internal command speed is disabled.
