Object 6073 : max_current
h
As a rule, servo motors may be overloaded for a certain time period. With this object, the maximum
permissible motor current is set as a factor. It refers to the nominal motor current (Object 6075
motor_rated_current) and is set in thousandths. The range of values is limited upward through the
maximum motor controller current (see technical data). Many motors may be overloaded briefly by a
factor of 4. In this case, the value 4000 is written into this object.
The object 6073
(motor_rated_current) was previously written with a valid value.

Object 604D : pole_number
h
The number of poles of the motor can be found in the motor data sheet or the parametrisation soft-
ware. The number of poles is always even. The number of pole pairs is often specified instead of the
number of pins. The number of poles then equals twice the number of pole pairs.
