6.9 Inverter operation
When operating the motors on the frequency inverter the inverter manufacturer's EMC notes must be observed.
Appropriate suppression measures must be taken. Metal shielded cables and cable glands should be provided.
The motor's torque depends on the respective inverter.
With brake motors the brake's rectier must be tted with a separate, sinusoid voltage.
The motor must be protected from excessive overheating by cold conductors, thermo contacts and/ or by external fans.
6.10 Motor protection
6.11 External fans
The voltage and wiring of the external fan are dierent depending on the type of fan.
The external fan has a separate terminal box.
Information on the voltage, frequency and wiring of the external fan is in this terminal box. These are dierent
depending on the size.
ATTENTION : Depending on the controls, the external fan may operate even if the motor is not turning.
Some external fans can only be operated in single phase.
Other fan motors can be operated both in single phase in a Steinmetz circuit and also in triphase.
3 phase motor: In a star circuit or a triangular circuit, depending on the voltage as in the section "Electrical con-
nection".
7. Commissioning the input drive
Before starting the gear motor, ensure that all safety regulations have been obeyed, the machine has been
installed and aligned properly, all fastenings and earth connections have been tightened properly, the auxiliary
and additional devices are working properly and have been connected properly and that the feather key on any
second shaft end key cannot be ung out. For oil-lubricated gearboxes, lling with suitable lubricant, as specied
in Chapter 8.2, must be ensured.
If possible, the gear box is to be started without load. If it runs quietly and without any odd noises, the motor is
attached to the driven machine. On starting up it is advisable to look at the currents being used when the motor
is connected to its driven machine so that potential overloads and asymmetries on the mains side can be detec-
ted immediately.
8. Lubrication notes
8.1 Lubrication
Grease lubricated CYCLO Drive 6000's are already lled with grease at the factory and are operated without top-
ping up. The type of grease used must not be mixed with other types of grease. The standard ESSO Unirex N2
grease (for lifetime lubrication) and Shell Gadus S2 V220 2 grease are suitable for ambient temperatures of
between -10 °C and +50 °C though the maximum surface temperature of the drive housing must not exeed 95
0
C.
Please contact SCG if you wish to use standard greases outside this temperature range or if you wish to use other
lubricants.
8.1.1 Lifetime grease lubrication
All type CN CYCLO Drive 6000's .. are greased for life and can be installed in any position. These gearboxes are
lled at the factory with ESSO Unirex N2 and do not need topping up. The lifetime can be increased if the grease
is replaced after 20000 hours or between 4 - 5 years.
Motor protection switches (overload protection) must be set to the current value specied on the rating plate
depending on the voltage.
Thermo contacts are normally designed as openers.
The resistance of cold conductors (PTC's) at 20 °C is not signicant. The value may vary between 60 Ω and a maxi-
mum of 750 Ω.
Ensure that all safety instructions have been explicitly obeyed once more.
Mains power conditions and the information on the rating plate must be the same. There is additional information
in the motor terminal box for additional equipment, such as standstill heating.
The cross section of the connection cables must be adapted to the motor currents.
The installation is subject to all regulations in force and must be done by qualied personnel.
