Func
tions
Absolute Position Control Mode
• To use this function, set V/f characteristics selection A044 to "05" (V2), and V2 control mode
selection P012 to "02" (APR2: Absolute position control).
• When "03" (high-resolution absolute position control) is selected in V2 control mode selection
P012, control is based on ×4 the number of pulses used for internal operations.
(Set the multi-step position command and position range setting for ×4 multiplication control.)
• The position command can be changed up to 8 steps, depending on combinations of multi-function
input terminals.
• Zero return speed can be selected from one low speed and two high speeds.
(The orientation function, described in the previous section, is not available.)
• By using the teaching function, you can set the position command while running the machine.
• By allocating "73" (SPD) to a multi-function input, you can switch between the speed and position
controls.
• For data with many digits (e.g. position command), only the higher 4 digits are displayed.
