No. Parameter 
544 Ramp modulating 
601 
Selection of reference point 
Index 0 = fuel 
Index 1 = air 
 
Setting values: 
0 = closed (<0°) 
1 = open (>90°) 
602 
Actuator's direction of rotation 
Index 0 = fuel 
Index 1 = air 
 
Setting values: 
0 = counterclockwise 
1 = clockwise (exclusively for SQM3) 
603  Tolerance limit of position monitoring (0.1°) 
Index 0 = fuel 
Index 1 = air 
 
Greatest position error where an error is securely detected 
→ Error detection band: (parameter 606 – 0.6°) up to parameter 606 
611 Type of reference 
Index 0 = fuel 
Index 1 = air 
 
Setting values: 
0 = standard 
1 = range stop in the usable range 
2 = internal range stop (SQN1) 
3 = both 
613 Type of actuator 
Index 0 = fuel 
Index 1 = air 
 
Setting values: 
0 = 5 s / 90° (1 Nm, 1,2 Nm, 3 Nm) 
1 = 10 s / 90° (6 Nm) 
2 = 17 s / 90° (10 Nm) 
 
Application note! 
Single-sided load torque is recommended due to the type of gear train for the 
SQM33.6 / SQM33.7 actuators. In the event of load on both sides, a backlash of 0.3° 
must also be considered in addition to plant design or setting
