2. Set the machine parameters according to the system constellation at hand.
3. After setting the machine parameters, click the Back button to change to the Overview dialog
level.
3.8.4.2 Set the position encoder
In the Lenze setting, the digital input terminals are configured as "normal" digital inputs. Since in
this system constellation DI1 and DI2 are used to connect a two-track position encoder, the function
assignment of these two inputs must be changed accordingly.
1. Go to the right side of the Application parameter tab and click the Signal flow button to change
to the Overview  Signal flow dialog level.
2. Click the Feedback system settings button in the signal flow:
Parameter Lenze setting Info
Value Unit
Mounting direction: Motor
( C01206/1 )
not inverted Inversion if motor mounting is mirrored.
Counter
( C01202/1 )
1 Gearbox factor - motor
• Entry of the gearbox factor as
numerator/denominator ratio (numerator = motor
speed and denominator = output speed of gearbox)
or from the number of teeth of the gearbox
arrangement.
Denominator
( C01202/2 )
1
Mounting direction: Position
encoder
( C01206/2 )
not inverted Inversion if position encoder mounting is mirrored.
Counter
( C01203/1 )
1 Gearbox factor - position encoder
• Entry of the gearbox factor as
numerator/denominator ratio, with numerator =
motor speed and denominator = position encoder
speed.
Denominator
( C01203/2 )
1
Axis cycle
( C01201/1 )
0.0000 units Cycle for Modulo measuring system
• The Modulo system is activated by setting a cycle
( C01201/1 ) > 0 units.
• When the cycle ( C01201/1 ) is set to 0 units (Lenze
setting), the traversing range is unlimited (classical
measuring system).
Feed constant
( C01204 )
360.0000 units/rev. The feed constant corresponds to the movement of the
machine during one revolution of the gearbox output
shaft.
• The value is entered in application units referred to
one revolution.
Reference speed
( C00011 )
1500 rpm All speed setpoint selections are provided in % and
always refer to the reference speed set in C00011 .
The motor reference speed is indicated on the motor
nameplate.
