Obviously, the voltages and frequencies quoted above are nominal values.
(2) Place the tester probes between the terminals 0 (signal) and L (ground) of the inverter. Check
that during machine operation the speed shown on the display and the voltage measured on the
inverter correspond to the values shown in Table 6.6-1 or in Table 6.6-2.
(3) See paragraph 9.4.
(4) Place the tester probes between pins 5 (signal) and 6 (ground) of connector CN1 on the
inverter interface board. Check that during machine operation the speed shown on the display
and the measured voltage correspond to the values shown in Table 6.6-1 or in Table 6.6-2.
(5) Place the tester probes between pins 10 (signal) and 3 (ground) of connector CN2 of the
inverter interface board. Check that during machine operation the speed shown on the display
and the measured voltage correspond to the values shown in Table 6.6-1 or Table 6.6-2.
(6) Place the tester probes between pins 6 (signal) and 3 (ground) of connector CN1 on the CPU
board. Check that during machine operation the speed shown on the display and the measured
voltage correspond to the values shown in Table 6.6-1 or in Table 6.6-2.
