Lenze 8200 Frequency inverters - Manual (Page 129)

Commissioning
8200SHB0199 5-24
Application FIG 5-4:
The material speed v
2
is to be synchronised to the line speed v
1
by means of a
dancer-position control. The dancer-position setpoint is internally set.
Functions used
-
Internal PID controller as position controller.
-
Selection of the line speed v
1
via terminal 8.
-
Actual dancer-position value from the dancer potentiometer via the analog
plug-in module 8279IB.
-
Set-up speed via terminal Klemme E3 (JOG1).
-
Switch-off of the influence of the dancer controller via terminal E4 (externally)
or internally via Q
min
(C017) and C008 = 7.

C005 Configuration -0- -6- Controlled operation; setpoint via
terminal 8 with digital frequency
feedback via terminal E1 Jumper setting for
terminal 8 must be
adapted to 5 V (see
chapter 4.2.8.2).
C007 Terminal configuration -0- -49- Actual dancer position
via terminal E1
C037 JOG value 1 20.00 Fixed set-up speed v

C105 Deceleration time QSP 5.00 Enter approx. 1 s E.g. emergency-off
function:
- The drive geometry
must be adjusted so
that it is possible to
brake the controller to
standstill within a very
short time. A brake
chopper might be
required.
C181 Setpoint PID controller 0.0 Set the dancer to the position required,
C051 = read the actual dancer value and
store it under C181. C181 must not be 0,
because here the
position setpoint is
generated by the main
setpoint.
C239 Frequency setting range -0- -1- Unipolar Direction of rotation
cannot be changed via
the process controller.
- All other parameters are based on the factory setting.
- Adapt the jumper setting to the main setpoint signal (see chapter 5.5.1).
- Set the rated motor data under C088 (rated motor current) and C091 (motor cos Ö) depending to the motor
connected.
