Flow diagram to commission a SIMODRIVE POSMO A
Define the dimension units (P4: 0 = mm, 1 = degr., 2 = inch)
Linear axis
Enter a gearbox step–down ratio (P3, e.g. for 1 : 4.5 ––> P3 = 4.5)
Traversing distance per revolution at the gearbox output (P2)
Determine the maximum velocity (P10 = P8 S P2/P3)
Define the maximum acceleration (P22).
The acceleration can be increased up to the drive current limit.
Define the software limit switch (P6, P7)
P6 = P7 ––> software limit switch de–activated
Set the monitoring functions
P12 (max. following error) P14 (standstill range)
Optimization?
The speed and position controllers are preset in the
factory and these settings should be adequate for
most applications. We recommend that the factory
presetting for P56.2 = 0 (holding controller active at
standstill) remains unchanged.

Prerequisites:
S
Start–up tool has been installed
S
Communications established
between the master and slave
Refer to the flow diagram, Fig. 3-12
yes
Modulo?
no
Enter the modulo value
Modulo value
(e. g. P1 = 360 degrees)
(P1 = 0)
The control loop parameters must be
adapted to optimize the system (refer to
Fig. 3-9).
Analog measuring outputs can be used to
support the optimization procedure (refer to
Chapter 6.3).
