11 Actuators X53 / X54 17.12.2018
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
