Master integrator (setpoint generation)
The setpoint path is designed according to the configurations 1XXX and 4XXX, but without inverting
the main setpoint via the terminals X5/E1,E2. This means:
l Main setpoint is generated by analogy via terminal X6/1, X6/2
l Additional setpoint is generated by analogy via terminal X6/3, X6/4 (when used, the additional
setpoint must be enabled via C0190)
In this configuration, the setpoint selection refers to the frequency at the master frequency output
X10.
Tip!
The resulting speed setpoint is output at the master frequency output X10. It is the setpoint in terms
of amount and direction of rotation for the following slaves. At the same time it is considered to be
the setpoint for slave 0 (included in the master drive), i.e. for the entire drive system.
The master drive consists of the master integrator and the slave 0. Slave 0 is the first drive at the
master frequency.
Master frequency output X10
The master frequency output simulates an incremental encoder with two 5 V complementary signals
shifted by 90°. The encoder constant (inc/rev.) can be set and scaled in code C0030. Here, the
encoder type 2048 inc/rev. is set as standard.
The output frequency is determined by the speed set in C0011 (n
max
) and the encoder constant.
Example:
C0011 = 5000 rpm, C0030 = 4
³ 4096 inc/rev. setpoint = 100 %
The output frequency is 341.3 kHz (5000/60s × 4096).
With higher speeds, e. g. 8000 rpm in this setting, the output frequency is 564.1 kHz. In this case,
the maximum possible output frequency of 500 kHz would be exceeded. Hence, an encoder
constant with a smaller number of increments must be selected.
Tip!
In principle, the highest possible frequencies should be selected since the 400 kHz range provides
the best resolution.
