6 Electrical Data
Note: The adjustable pulse frequency (4, 8, 12 resp. 16 kHz)
depends on the firmware and the control section.
The capacity of the drive controllers is described below with examples of
load profiles. The examples distinguish applications for servo operation
(400 ms) and main spindle operation (2 s resp. 60 s).
Note: The load profiles are characterized by their time flow and the
corresponding currents and represent the output current
capacity. These profiles are limited by the drive controller via
the thermal effect of the output current. When the current
limitation is triggered, it is therefore necessary to
• reduce the load with I
out_peak
or
• reduce the pulse time or
• increase the cycle time or
• use a device with higher type current
(See also Functional Description and Troubleshooting Guide
of the firmware.)
Note: The load profiles are available if particularly the maximum
current at switching frequencies of 8, 12 and 16 kHz is
externally (e.g. by the NC) limited to the indicated values.
