5 General concepts
n
velocity
=
2062
h
2061
h
When entering values, the following applies correspondingly: Internal value = n
speed
x input value
When outputting values, the following applies correspondingly: Output value = internal value / n
speed
Example
h
h
is set to the value "60" (default). Thus, the user unit is
"revolutions per minute" and n
speed
= 1/60.
If 60FF
is written with the value "300", the internal value is set to 300 rpm x 1/60 = 5 rps.
If the motor turns at an internal speed of 5 rps, object 606B
is set to a speed of 5 / 1/60 =
300 rpm.
Acceleration
The acceleration can also be specified in user units:

"Quick stop active" state (CiA 402
Power State Machine)
Braking deceleration
The internal unit is revolutions per second
2
(rps
2
).
The factor n for the acceleration is calculated from the scaling factor for the numerator (2063
h
) divided
by the scaling factor for the denominator (2064
).
When entering values, the following applies correspondingly: Internal value = n
acceleration
x input value
Example
h
h
is set to the value "60". Thus, the user unit is revolutions
per minute per second and n
acceleration
= 1/60.
If 60C5
h
is set to the value "600", the internal value is set to 600 rp(s*min) x 1/60 = 10 rps

.
or object 2064
h
is set to "0", the firmware sets the value to "1".

h
can be specified in user units. These objects only affect
Profile Position Mode and Profile Velocity Mode.
