G2: Velocities, setpoint / actual value systems, closed-loop control
7.2 Velocities, traversing ranges, accuracies
The following applies:
Selected input/output unit = MD10230 * internal unit
In the machine data:
MD10230 $MN_SCALING_FACTORS_USER_DEF[n]
the selected input/output unit printed in each case in the internal units 1mm, 1 degree and 1 s must be input.
Example 1:
Machine data input/output of the linear velocities is to be in m/min instead of mm/min (initial state).
(The internal unit is mm/s)
⇒ The scaling factor for the linear velocities is to differ from the standard setting. For this
in the machine data:
MD10220 $MN_SCALING_USER_DEF_MASK
the bit number 2 must be set.
⇒ MD10220 $MN_SCALING_USER_DEF_MASK = 'H4'; (bit no. 2 as hex value)
⇒ The scaling factor for the linear velocities is to differ from the standard setting. For this
in the machine data:
MD10220 $MN_SCALING_USER_DEF_MASK
the bit number 2 must be set.
⇒ MD10220 $MN_SCALING_USER_DEF_MASK = 'H4'; (bit no. 2 as hex value)
