8.2 Permissible cycle times if operating with an FC frequency converter

We recommend using a frequency
converter in regions with 230 V
(1-phase)/400 V (3-phase) line voltage:
• Bosch Rexroth IndraDrive Fc 230 V,
0.37 kW (R911311055)
• Bosch Rexroth IndraDrive Fc 400 V,
0.55 kW (R911311061)
The frequency converter is supplied with
a standard I/O module. Further available
modules:
• PROFIBUS DP (R911311072)
• CANopen (R911311074)
• DeviceNet (R911311075)
Technical data:
• T : 0–50°C (in control cabinet)
ambient
• Protection class IP20 (control cabinet
installation)
• Altitude  1000 m above sea level.
At higher altitudes, performance
decreases by 1% for each 100 m of
altitude.
Please ask your Rexroth representative
for more information on other operating
conditions.
The section load of 0.08 kg/cm per track
must not be exceeded.
Read the permissible weight and
operating time in the preferred direction
in diagram 1 or 2. The operating
time (OT) is valid for a travel time of
3 sec  t  20 sec. For data applying
Travel
to reverse operation, ask your Rexroth
representative.
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 operating
time must not exceed 44%. If there is a
lower number of cycles, the permissible
relative operating time will increase
accordingly, see diagram 3.
The diagrams apply to an ambient
motor temperature of 25°C. The motor
temperatures may reach 60°C at the
maximum number of cycles. Please
ask your Rexroth representative for
more information on other operating
conditions.
Permissible length of the shielded motor
cable: max. 20 m
