Commissioning and operation

Important notes
Stop!
The drive may only be commissioned by skilled personnel!
¯
Before commissioning remove transport locking devices and keep them for later
transports.
¯
Take safety measures prior to any operation:
–
Disconnect the machine from the mains, ensure standstill of the drive system
and avoid any machine movement.
–
That the ambient temperature match the data on the nameplate.
Follow the instructions specified for the temperature ranges.
Temperature range
Standard
Ambient temperature
0 °C ... +40 °C
Lubricant
Mineral oil

CLP 460
Synthetic oil

CLP HC 220
Food−compatible oil
¯
CLP PG 460 USDA H1
Note
At an ambient temperature mainly above +30 °C
¯
Application case must be verified by Lenze
Low−temperature
Ambient temperature
−30 °C ... +10 °C
Lubricant
Food−compatible oil
¯
CLP HC 46 USDA H1
Note
When starting up a cold motor, increased starting torques are to be expected at
temperatures below −20 °C due to the higher viscosity of the roller bearing grease.
¯
During project planning, allow a motor starting torque reserve of about 20 %.
Commissioning at over +10 °C:
¯
Operate the drive at max. 50 % of the rated torque to avoid a reduction in service life.

At an ambient temperature mainly above +30 °C:
¯
Individual case must be verified by Lenze!
At a continuous temperature of between −30 °C and −25 °C, the service life is up to 20 %
shorter than with the low−temperature range.
