YASKAWA ELECTRIC SIEP C730600 89C YASKAWA AC Drive Option SI-EP3 Technical Manual 53
 Option Fault Monitors U6-98 and U6-99
The option can declare error/warning conditions via drive monitor parameters on the drive keypad as shown in Table 31.
Table 31 Option Fault Monitor Descriptions
Two drive monitor parameters, U6-98 and U6-99 assist in network troubleshooting:
• U6-98 displays the first declared fault since the last power cycle. U6-98 is only cleared upon drive power-up.
• U6-99 displays the present option SI-EP3 status. U6-99 is cleared upon a network-issued fault reset and upon
power-up.
If another fault occurs while the original fault is still active, parameter U6-98 retains the original fault value and U6-99
stores the new fault status value.
 Option Compatibility
Users may connect up to 3 options simultaneously depending on the type of option.
