If short-circuit braking is to be used as the only holistically effective deceleration unit, it is
recommended to verify the feasibility by tests. For this purpose, bit 6 in the Lenze control word
(0x2830
or 0x3030 for axis B) serves to trigger the short-circuit braking. The oscilloscope function of
the »PLC Designer«/»EASY Starter« serves to record the following important objects:
•Speed: Setpoint speed (0x2DD3:1
or 0x35D3:1 for axis B)
• Speed: Actual speed (0x606C
or 0x686C for axis B)
• Phase currents U, V, W (0x2D83:2...4
or 0x3583:2...4 for axis B)
5.17 Setting the switching frequency
The i700 servo inverter can be operated with the switching frequencies listed below.
0x2939 | 0x3139 - Switching frequency
Note: In case of "8 kHz var." and "16 kHz var.", variable switching frequencies are involved. If the permissible
continuous current for the respective switching frequency is exceeded, it is automatically switched back to the next-
lower switching frequency.
