is to be set to "0", the firmware sets the value to "1".
Acceleration
The acceleration can also be output in user units:

Meaning
Homing mode
Acceleration
h
Profile Position Mode

Profile Position Mode
Deceleration
Profile Velocity Mode

"Quick stop active" state (DS402 Power
State machine)
Deceleration
The internal unit for acceleration is rounds per second
2
.
The factor n for the acceleration is calculated by the factor for the numerator (2063
h
) divided by the
factor for the denominator (2064
).

For the input of values it is applied: internal value = n

to the value "60". Therefor the user unit is "rounds per
second per minute" and n

= 1/60.
h
gets set to the value "600", the internal value will get set to 600 r/(s*min) x
1/60 = 10 r/s

can be specified in user units. These objects only affect the
Profile Position Mode and Profile Velocity Mode.
The internal unit for jerk is rounds per second

The factor n for the acceleration is calculated by the factor for the numerator (2065
