Procedure
1.
Parameter p0009 on the Control Unit must be set to 3 "Basic drive configuration".
2.
Parameter p0112 "Sampling times default setting p0115" of the DO VECTOR must be set
to 0 "Expert".
3.
Use p0113 to enter any pulse frequency between 1 kHz and 2 kHz. If a higher pulse
frequency is to be set (e.g., 2.2 kHz), this value must be divided by 2 or by 4 to obtain a
result between 1 kHz and 2 kHz (e.g., 2.2 kHz divided by 2 is 1.1 kHz).
4.
Not all pulse frequencies are accepted in parameter p0113; in such cases, the alarm
"Impermissible value" is output.
5.
If the frequency entered in parameter p0113 is not accepted, parameter r0114[0]
recommends a different frequency that can deviate from the entered pulse frequency by
several Hertz. This frequency should be entered in p0113.
6.
After entering the frequency in p0113, parameter p0009 on the Control Unit must be set
to 0 "Ready" again.
7.
The Control Unit re-initializes. After booting, the pulse frequencies recommended in
r0114[i] (i = 1, 2, ...) can be entered in parameter p1800 "Pulse frequency" of the DO
VECTOR.
Note
Entering the pulse frequency
The pulse frequency entered in p1800 must correspond precisely to the value given in
r0114[i]; otherwise, the entry will be rejected.
9.2.10.4
Maximum output frequency achieved by increasing the pulse frequency
By multiplying the basis pulse frequency (with integers), the following output frequencies can
be achieved (taking into account the derating factors):
