Once started, the test function is automatically cancelled if s reaches  6 %.
Nonetheless, it is recommended that you prepare for any manual cancellation by noting
the following key combination:
&
&
&
If the frequency matcher is used with the INVERSE f function, the test function makes
no sense and is therefore blocked.
Procedure
1. Start conditions: - Running machine
- U1 and f1, both between 95 % and 105 %,
- U2 and f2, both between 85 % and 115 %
- Corresponding parameter set selected
- SYNCHROTACT 5: parameter INVERSE f = OFF
- Device blocked (blocking: see section 7)
2. Change address to parameter TEST f-Match in the corresponding parameter set in
the parameter group “Frequency Matcher“
3. Set TEST f-Match to ON
4. Confirm with &
5. Enable the test function by pressing: & &
6. Start the test function within 30 s following enable: &
7. Wait for end of test function (1 to 2 minutes), then read result for df/dt
8. Change address to parameter df/dt (1* ) and set read value
9. Write the value into the random access memory by pressing: &
10. Return to TEST f-Match, set this to OFF and confirm with &
11. Temporarily set SYNCHROTACT 5 to “Ready“and block again. This writes all
parameter settings into the ROM.
If repeated use of the test function does not lead to a reasonable result, the setting value
should be determined empirically as described below.
Frequency adjusting characteristic df/dt
Factor for the command length which is formed proportionally to the slip. The setting
value is determined using the test function TEST f-Match. Usual setting values: 0.1 to
0.5 %/s. The adjusting pulses are suppressed if df/dt is set to zero.
Empirical determination of the setting value:
Aim: a single frequency adjusting command should bring the slip approximately to half of
the maximum slip smax. To do this, the frequency matcher must adjust the machine by
means of frequency adjusting commands. The operator checks the command length
and corrects it if necessary until the matcher is functioning satisfactorily.
