Bit0: Position deviation mode
0: No deviation
1: With deviation
Bit1: Enable/disable servo
0: Disable (The servo can be enabled by terminals.)
1: Enable
Bit2: (reserved)
Note:
In the pulse string or spindle positioning mode,
the inverter enters the servo operation mode when
there is a valid servo enabling signal. If there is no
servo enabling signal, the inverter enter the servo
operation mode only after it receives a forward
