■ S6-10: Overacceleration Detection Level
If the elevator car accelerates at an abnormal rate, the drive triggers an overacceleration fault (dv6) and the motor coasts
to stop. Parameter S6-10 determines the acceleration rate that triggers the dv6 fault. A setting of 0.0 m/s
2
disables
overacceleration detection.
■
S6-11: Overacceleration Detection Time
Sets the time that the acceleration must exceed the overacceleration detection level before as fault is triggered.
■
S6-12: Overacceleration Detection Selection
Determines the conditions for detecting an overacceleration situation.
Setting 0: Always enabled
Setting 1: During run only
■ S6-15: Speed Reference Loss Detection
Enabled or disables detection for missing speed reference (FrL).
Setting 0: Disabled
Setting 1: Enabled
■ S6-16: Restart after Baseblock Selection
Allows the drive to restart the motor after returning to normal operation from Baseblock state (H1- = 8/9) or from
Safe Torque-Off state (Safe Disable inputs H1 and H2 enabled) while the Up/Down command is still active.
Setting 0: No restart after Baseblock or Safe Torque-Off
Do not restart the motor when leaving the Baseblock or Safe Torque-Off state even if an Up/Down command is still
active.
Setting 1: Restart after Baseblock or Safe Torque-Off
Restart when the Up/Down command is still active while the Baseblock or Safe Torque-Off state is left. To use this
function with the Safe Disable function, parameter L8-88 must be set to 1.
◆ T: Motor Tuning
Auto-Tuning automatically sets and tunes parameters required for optimal motor performance. Refer to Auto-Tuning on
page 112 for details on Auto-Tuning parameters.
No.
<1> Default setting is determined by parameter o1-03. If o1-03 is set to 0 through 5, the default is 1.5 m/s

. If o1-03 is set to 6, the default is 5.0 ft/
s
