- To use the absolute position control mode function, specify
"05" (V2) for V/F characteristic curve selection, 1st motor (A044)
and "02" (APR: absolute position control) for the control pulse
setting (P012).
- If "03" (high-resolution absolute position control) has been
specified for the control pulse setting (P012), the quadruple
number of pulses used for internal operations is applied to the
control. (Then, specify values of quadruple precision for the
multistage position settings and position range specification.)
- Position settings can be switched in up to eight stages in
combination with control pulse settings.
- You can select zero-return mode from one low-speed and two
high-speed modes.(The home search function described in t
preceding section cannot be used.) he
- The teaching function allows you to specify position settings
while actually running the machine.
- If function "73" (SPD) is assigned to an intelligent input
terminal, you can switch between the speed control and
position control modes during operation.
- Only the four high-order digits of data are displayed when the
data (e.g., position setting) to be displayed consists of a large
number of many digits.
