102 YASKAWA ELECTRIC TOEP C710616 38F YASKAWA AC Drive L1000A Quick Start Guide
■ S5-01: Short Floor Operation Selection
Enables and disables the Short Floor function.
Note: 1. The Short Floor and Advanced Short Floor functions cannot be used during Rescue Operation.
2. Do not use Short Floor or Advanced Short Floor when the analog input terminals are configured to supply the speed reference.
3. The drive will accelerate or decelerate to the specified speed reference at the specified Accel/Decel rate if the speed priority is set for
multi-step speed reference (d1-18 = 0 or 3) and the leveling speed reference is selected during Short Floor or Advanced Short Floor.
Setting 0: Disabled
Setting 1: Enabled (Short Floor Operation)
Setting 2: Enabled (Advanced Short Floor Operation)
■ S5-02: Nominal Speed for Short Floor Calculation
Determines the rated speed used to calculate the distance for the Short Floor function when speed priority is set for Multi-
step Speed Reference (d1-18 = 0 or 3).
■ S5-03: Short Floor Minimum Constant Speed Time
Sets the minimum time of the constant speed operation when the Advanced Short Floor function is enabled (S5-01 = 2).
■ S5-04: Distance Calculation Acceleration Time Gain
Sets the gain used to adjust the jerk at acceleration for an optimum speed calculation when Short Floor Operation
Selection (S5-01) is set to 2.
• Increase the gain level set to S5-04 and S5-05 if the leveling time is too short or if the optimum speed calculated by the
drive is too fast.
• Decrease the gain level set to S5-04 and S5-05 if the leveling time is too long or if the optimum speed calculated by the
drive is too slow.
Note: Setting S5-04 too low may trigger an overrun due to faster optimum speeds and shortened leveling times. Avoid setting this gain
less than 100%.
■ S5-05: Distance Calculation Deceleration Time Gain
Sets the gain used to adjust the jerk at deceleration and optimum speed calculation when Short Floor Operation Selection
(S5-01) is set to 2.
• Increase the gain level set to S5-04 and S5-05 if the leveling time is too short or if the optimum speed calculated by the
drive is too fast.
• Decrease the gain level set to S5-04 and S5-05 if the leveling time is too long or if the optimum speed calculated by the
drive is too slow.
Note: Setting S5-05 too low may trigger an overrun due to faster optimum speeds and shortened leveling times. Avoid setting this gain
less than 100%.
