Figure 5.9 Operation Wait Time Depending on Output Frequency
Setting 9: Simple Positioning Stop
This method of stopping the motor always decelerates the same distance to stop as shown in
Figure 5.10
. The stopping
distance S1 is calculated using the maximum output frequency setting E1-04 and the selected deceleration time. If the
drive is stopped from a frequency lower than the maximum speed it keeps the current speed. When the distance traveled
becomes equal to S1 - S2, the drive decelerates to stop using the current deceleration time. The stopping accuracy can be
adjusted using the positioning gain set in parameter d4-12.

Figure 5.10 Simple Positioning Deceleration
Precautions when using Simple Positioning:
• Changing the deceleration time during the deceleration will result in inaccurate positioning as the calculation considers
the deceleration time that was active only when the Run command was removed.
• The Dwell function must be deactivated (b6-03 and b6-04 = 0).
• The KEB function can not be used (H1-
must be different than 65/66/7A/7B).
• The Stall Prevention during stop must be deactivated (L3-04 = 0). For regenerative loads a braking option might be
necessary.
• The overvoltage suppression must be disabled (L3-11 = 1).
• High Slip Braking must be deactivated (H1-
must be different from 68).
• The S-curves at deceleration start and deceleration end must be inactive (C2-03/04 = 0).

b1-04: Reverse Operation Selection
For some applications, reverse motor rotation is not appropriate and may even cause problems (e.g., air handling units,
pumps, etc.). Setting parameter b1-04 to 1 instructs the drive to ignore any Reverse run commands.

The drive has the following three separate control sources that can be switched using digital inputs or the LO/RE key on
the digital operator (for details
