Characteristic curves
Required power reduction
Mounting clearances may be required at output currents > 4.6 A to ensure the device reaches its
specified service life. The required mounting clearances depend on the ambient temperature and the
output current.
Mounting clearances from 0 mm are possible for a device compound consisting of several servo drives
CMMT-ST. The following characteristic curves show the maximum permissible effective currents for the
lateral mounting clearances 0 mm, 3 mm, 10 mm and 15 mm.
