MMC Smart Drive Hardware Manual - MAINTENANCE AND TROUBLESHOOTING
• The 230V smart Drive, 460V Smart Drive, and S200-DLS contain a Diagnostic
LED (D1) that is located on the front of the Drive. This Diagnostic LED is covered
in detail in section 10.2.4.1 on page 247.
• The 460V Smart Drive NextGen contains a 2-digit 7-segment display that is
located on the front of the Drive. This display is covered in detail in section
10.2.4.2 on page 247.
• The S200-DLS contains an additional Status LED (labeled "STATUS"), that is
located on the front of the Drive. This Status LED is covered in detail in section
10.2.4.3 on page 255.
10.2.4.1 Troubleshooting with the Diagnostic LED (D1)
This section pertains to the Diagnostic LED labeled "D1" located on the front of the
230V Smart Drive, the 460V Smart Drive, and the S200-DLS Drive. The S200-DLS
Drive also has a Status LED, labeled "STATUS", which is covered in section 10.2.4.3
on page 255.
When a Warning or Fault is detected, the Diagnostic LED (D1) located on the face of
the drive will flash a one-digit Warning Code or a two-digit Fault Code. The LED will
continue to flash the Code until the Warning or Fault is eliminated.
For example, if there is a long pause-flash-pause-flash-flash-long pause, the Code is
12.
Warning conditions give the user an indication of a potential problem, but do not
disable the drive. Whenever a Warning condition is detected, the drive generates a
single-digit Warning Code. The user can detect a Warning condition in three ways:
• by visually observing the "D1" LED on the front of the Drive
• by examining the Drive Maintenance page in PiCPro under “Faults and Warnings”
• by reading the Warning Code using READ_SV variable 69 from within the user’s
Ladder.
Fault conditions give the user an indication of a more serious problem, and disable
the Drive. Whenever a Fault condition is detected, the drive generates a two-digit
Fault Code.
The Drive Diagnostic Codes are described in Table 10-2.
10.2.4.2 Troubleshooting with the 7-Segment Display
This section pertains to the 7-segment display located on the front of the 460V Smart
Drive NextGen.
When a Warning or Fault is detected, the Display located on the face of the drive will
indicate a one-digit Warning Code or a two-digit Fault Code. The code will remain on
the Display until the Warning or Fault is eliminated.
Warning conditions give the user an indication of a potential problem, but do not
disable the drive. Whenever a Warning condition is detected, the drive generates a
single-digit Warning Code. The user can detect a Warning condition in three ways:
• by visually observing the Display on the front of the Drive
• by examining the Drive Maintenance page in PiCPro under “Faults and Warnings”
