(S-Curve Abort)  
This parameter, S-CURVE ABORT (C1), 
addresses how the S-Curve Speed Reference 
Generator handles a reduction in the speed 
command before the S-Curve Generator has 
reached its target speed.    
Disabled: With a normal S-curve function, a 
change in the speed command is never allowed 
to violate the defined acceleration or jerk rates.  
If a reduction in the speed command is issued 
before the S-Curve generator has reached its 
target speed, then the jerk rate dictates what 
speed is reached before the speed may be 
reduced. 
Enabled: The optional S-Curve abort has been 
selected. In this case when the speed command 
is reduced, the speed reference immediately 
starts to reduce violating the jerk limit (thus no 
jerk out phase), which could be felt in the 
elevator. 
For optional S-Curve abort to be active requires 
that: 

•  The speed command source must be 

selected as Multi-step (SPD COMMAND 
SRC=multi-step). 

•  The S-curve Abort function must be 

ENABLED (S-CURVE ABORT = enabled).

(Encoder Fault Enable)  
This parameter allows the user to temporarily 
disable the Encoder Fault.  Adding this feature 
allows the user to temporarily disable the 
Encoder Fault during the initial start-up process, 
when the motor model (defined by the A6 Motor 
Parameters) is not clearly defined. 
When the Encoder Fault is disabled (ENCODER 
FAULT (C1) = disabled), the drive will display 
the warning message “EncoderFault OFF”, 
every time the RUN command is removed. 
IMPORTANT:  After the motor parameters in A6 
have been established, the Encoder Fault 
should be enabled (ENCODER FAULT (C1) = 
enabled). 
Note: the default for the ENCODER FAULT (C1) 
parameter is enabled.

(Priority Message Enabling)   
With Priority Message disabled the user will not 
see priority messages meaning faults and 
alarms will not be displayed on the operator, but 
the faults will be placed into the fault history and 
active fault lists with the Fault LED on.  Leave 
Priority Message enabled when drive is not 
being worked on.
