6.5.1 Running Velocity control
To use the JVL motor in velocity -mode the following registers basically is of interest.
1. "Mode" - mode register - register 2
2. "V_SOLL" - velocity register 5
3. "A_SOLL" - acceleration register 6
4. "Error/Status" - register 35
So, to control these registers the assembly object needs to be configured.
From MacTalk the setup is configured as this.
With the settings illustrated above we initiate the velocity mode by writing 0x1 to
the first word-value, this is velocity mode.
Since different PLC's have different methods of implementation the basic steps is
described in the following.
(Constant values valid for MAC800, for other motors,
please consult the motor manual)
1.
Set the needed velocity
.
V_SOLL = V x 2.77 [rpm].
Example: We need the motor to run with a constant speed of 1200 RPM.
So, V_SOLL = 1200/2,77 = 433 cnt/smp
2.
Set the needed acceleration.
A_SOLL = A x 271 [RPM/s2].
Example: We need the motor to accelerate with 100000 RPM/s2 so, A_SOLL
= 100000/271 = 369 cnt/smp2
3.
Now set the motor in velocity mode and thereby activate the motor.
Example: The motor needs to be activated by setting it into velocity mode, so
we need to set the mode register to the value 1. Mode = 1 which is velocity
mode, now the motor will use the acceleration and the velocity just config-
ured.
