Overload protection
If the upper load limit is exceeded, the motor
automatically compensates for this by reducing the
speed and stops if the overload condition persists.
The motor remains stopped for a set period. After
this period, the motor automatically attempts to
restart. The overload protection prevents damage to
the motor. Consequently, no additional motor
protection is required.
Overtemperature protection
The electronic unit has a built-in temperature sensor
as an additional protection. When the temperature
rises above a certain level, the motor automatically
compensates for this by reducing the speed and
stops if the temperature keeps rising. The motor
remains stopped for a set period. After this period,
the motor automatically attempts to restart.
Protection against phase unbalance
Connect three-phase motors to a power supply with
a quality corresponding to IEC 60146-1-1, class C, to
ensure correct motor operation at phase unbalance.
This also ensures long life of the components.
7.5 Functional modules
Various functional modules are available:
• basic functional module, FM 100
• standard functional module, FM 200
• advanced functional module, FM 300.
The selection of module depends on the application
and the required number of inputs and outputs.
7.6 Connection terminals on functional
modules
The descriptions and terminal overviews in this
section apply to both single- and three-phase
motors.
For maximum tightening torques, see section
Torques, page 60.
7.6.1 Basic functional module, FM 100
The module has only the most necessary inputs for
closed- and open-loop operation. The module also
enables communication via a GENIbus connection.
The module has these connections:
• analog voltage input
• two digital inputs or one digital input and one
open-collector output
• GENIbus connection.
See fig. 10.
• Inputs and output
The inputs and output are internally separated from
the mains-conducting parts by reinforced insulation
and galvanically separated from other circuits. All
control terminals are supplied by protective extra-low
voltage (PELV), thus ensuring protection against
electric shock.
• Mains supply (terminals N, PE, L or L1, L2, L3,
PE).
Digital input 1 is factory-set to be start/stop
input where open circuit results in stop. A
jumper has been factory-fitted between
terminals 2 and 6. Remove the jumper if
digital input 1 is to be used as external
start/stop or any other external function.
DANGER
Electric shock
- Death or serious personal injury
- Make sure that the wires to be
connected to the connection groups
below are separated from each other by
reinforced insulation in their entire
lengths.
