Acceleration and braking times of at
least 0.5 s are included in the cycle
times. To ensure suffi cient self-
cooling of the motors, the motor
frequency must not fall below 16 Hz
when at a standstill.
With 10 cycles per minute, the
relative operating time may be
max. 44%. If there is a lower
number of cycles, the permissible
relative operating time will increase
accordingly, see diagram 3.
The diagrams apply to a motor
ambient temperature of 25°C. The
motor temperatures may exceed
60°C at the maximum number of
cycles. Please ask your Rexroth
representative for information on
other operating conditions.
Permissible length of the shielded
motor cable: max. 20 m
