8.2
Mounting the force sensors
Mounting of the force sensors is done referring to the FMS Installation manual which is
delivered together with the force sensors.
Wiring to the terminals of the electronic unit is done according to wiring diagram (fig. 6
resp. 7).
Notice
Connecting the shield of the signal cable to the electronic unit
and
to the force sensor
may cause ground circuits which may interfere the measuring signal massively.
Malfunction can be the result. The shield should be connected only to the electronic unit.
On the „force sensor side“, the shield should stay open.
8.3
Mounting the drive unit
The motor and the drive power amplifier will be mounted according to manufacturer’s
specification. (If an AC drive unit is used, the energy produced in the motor while
braking must be led off to a brake resistor or equivalent.)
Connection of the power amplifier to the Tension Controller’s output terminal is done
according to the wiring diagram (fig. 6 resp. 7).
Danger
The tension controller can operate drives with high performance. It has no built-in
emergency stop function. To provide safety of man and machine in case of malfunction,
the person responsible for system design has to establish specific safety procedures such
as emergency stop ciruits, etc.
8.4
Mounting the tacho generator
If the control loop is operated with line speed overlay, the actual line speed has to be
transmitted to the electronic unit. For this purpose the actual line speed is detected with a
tacho generator and the line speed signal is fed to the analog line speed input (terminals
d6 / d8 resp. 7 / 8).
The tacho generator is mounted according to manufacturer’s specification.
A other 0...10V signal proportional to the line speed may be used too (for ex. from a
PLC) instead of the tacho generator
