5.11 S: Elevator Parameters
■ 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 o f 0.0 m/s2 disables
overacceleration detection.
No.
Parameter Name
Setting Range
Default
S6-10
Overacceleration Detection Level
0.0 to 20.0 m /s2
1.5 m /s2 <1>
<1> D efault setting is determined by param eter o1-03. I f o1-03 is set to 0 through 5, the default is 1.5 m /s2. I f o1-03 is set to 6, the default is 5.0 ft/
s2 (setting range: 0.0 to 50.0 ft/s2).
■ S6-11: Overacceleration Detection Time
Sets the time that the acceleration must exceed the overacceleration detection level before as fault is triggered.
No.

■ S6-16: Restart after Baseblock Selection
Allows the drive to restart the motor after returning to normal operation from Baseblock state (Н1-ПП = 8/9) or from
Safe Torque-Off state (Safe Disable inputs H1 and H2 enabled) while the Up/Down command is still active.
No.
Parameter Name

Default
S6-16
Restart after Baseblock Selection
0 or 1
0
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.
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.
