Debug Mode; Monitor Mode - Hitachi L300P Series Service Manual

3.Debug Mode

Additional displays as follows can be seen by turning Debug mode ON (C091 ->1).

3.1 Monitor mode

No Functional
1 Control frequency monitor
2 Direct-current voltage monitor
3 BRD on-monitor
4 Electronic thermal monitor
5 Gate array trip factor monitor
6 MCU No. monitor
d101 ( Output frequency monitor (Hz)): Monitor of the output frequency of the inverter.
d102 ( DC bus voltage monitor (V)): Monitor of the DC bus voltage (VPN) of the inverter.
d103 ( BRD ON monitor (s)): There is an integrated BRD circuit on 11kW and less for SJ300, and 15kW and less
d104 ( Electronic thermal monitor (%)):You can find the usage ratio of electronic thermal performance as %.
d105 (Trip cause monitor of gate array):There are 8 items of trips which are detected by the internal gate array
Bit7 bit6
Gate array IGBT error
error W phase
(E23) (E30)
Contents of d105 are expressed in HEX.
(Example 1)
20
20 (HEX) = 00100000 (BIN)
bit5 = "1" -> IGBT error (V phase)
(Example 1)
62
62 (HEX) = 01100010 (BIN)
bit1, bit5, bit6 = "1 " -> IGBT error (U, V, W phase)
d106(MCU No monitor): Display the software management number of MCU incorporated.
