and Pan speed commands to angle unit.
Command 005Bh
Length 1 byte Parameter
Value 0h
Length 4
byte Status
Value 11250 (2BF2h)
Reference •To return integral value multiplied 100000 to the conversion coefficient of
true Pan angle. In case of angle conversion, divide it by 100000.
Example below,
Status value /100000 = 11250 /100000 = 0.1125
Note: The parameter of 12.1 Pan Speed Assignment command can be
converted as under.
Pan speed = 800PPS = 800 × 0.1125 = 90 degrees/s

In case of Mode Error : 10010000B ⇒ 90h ⇒ 39h 30h
Condition of Error flag to be set
Parameter Error •Assign illegal parameters.
Mode Error
