ƒ
Motor power required
First, the maximum torque required M
max
, the maximum
speed n
max
, the effective torque M
eff
and - for geared
motors - the transmission ratio i are determined from the
system data.
ƒ
Motor selection
Based on these values, the appropriate servo motor can
be selected from the MCS or MD
☐
KS (synchronous mo-
tors),MCAorMDFQA(asynchronousmotors)ranges.More
detailed information can be found in the Servo Motors
catalogue.
Overload mode: 3 min cycle
ƒ
Axis module selection
The selection of the axis module is determined by the
maximum currents and the power required.
The overload capacity of the axis modules is dimensioned
according to the following overload mode:
3 min cycle
A: 1 min load period with max. 150% of output current
B: 2 min recovery period with 75% of rated current
For 9321 - 9325, 10 s with 200% of output current and 50
s with 44% of output current
