Meas.System:
Axis type:
Reference I The drive begins a reference point approach at this speed. Reference
speed 1: speed 1 is the higher of the two speeds for the initial approach to
reference point, and must be less than or equal to the maximum speed.
Reference I The IP 266 requires this speed for an exact approach to the reference
speed 2: point. Reference speed 2 must be less than or equal to the maximum
speed and less than or equal to reference speed 1.
Reference I Defines the direction for the reference point approach. Use <F7> to
direction: choose between 'forward' and 'reverse'.
Pulses/ I Specifies the number of pulses per encoder revolution (this information
revolution: can be obtained from the encoder's rating plate).
Travel/ I The distance traversed per encoder revolution must be entered in this
revolution: field. The value must take into account all ratios between encoder and
axis.
PLC BCD coded: I When you select "yes" with <F7>, all coordinates transferred from the
PLC are interpreted in BCD code. The value range in BCD format is
restricted to +/-9999999 µm.
Polarity HW limit I This field is used to indicate which edge of the limit switch or "External
switch: Stop" signal is to be evaluated.
"Type" column: I = input field, O = output field
The "travel/pulses" resolution is computed from the values for "travel/revo-
lution" and "pulses/revolution"
