Current dead zone data
This parameter data is determined by the amplifier being used.
When spindle switching control is used, a nonstandard amplifier, which
does not match the motor, may be used.
In such a case, modify the data according to the amplifier being used.
Note that if invalid data is set, the switching element of the power circuitry
may be damaged.

Standard setting : 75
This data is used to set the detecting range of speed zero detection
signal (SSTA).
When the motor speed reaches (setting data/100)% or less of maximum
speed, the bit of speed zero detection signal (SSTA) is set to ”1”.

Data unit :
Data range : 0 to 32767
Standard setting : Depends on the motor model.
When spindle switching control is used, a nonstandard amplifier, which
does not match the motor, may be used.
In such a case, modify the setting of this parameter according to the
conversion formula below.
