Keyboard Pass Numbers
Keyboard-measurement data is collected both for pedal phases and for drive-current phases.
1. Pedal phases
• UP models: 01 to 04
• GPs , MPX70: 01, 02
• DGP211XG, DGT7: 01---jaiat
2. Drive-current phases
Five phases: PHS 01 (minimum pressure) to PHS 05 (maximum pressure)
• The location of the PASS number on the display identifies the pedal phase that generated the problem.
• The value of the PASS number indicates the drive-current phase that generated the problem.
• The ten’s digit of the PASS number indicates the severity of the problem. (Higher values indicate more serious problems.)
PASS
No.
Data Used for Table Calculation Cause What to Do
00 Normal Velocity PHS 1–5
01 Velocity PHS 2 was abnormal Velocity PHS 1, 3, 4, 5 Pedal movement problem
Acoustic adjustment problem
Hammer Sensor problem
Pedal Acoustic Adjustment
Pedal Measurement
Piano Acoutic Adjustment
Check the Hammer Sensor (Sensor test)
02 Velocity PHS 3 was abnormal. Velocity PHS 1, 2, 4, 5
03 Velocity PHS 4 was abnormal. Velocity PHS 1, 2, 3, 5
04 Velocity PHS’s 2 and 4 were abnormal. Velocity PHS 1, 3, 5
10, 20, 30 Velocity PHS 1 measurement value = 0
10 to 19: Use data from preced-
ing same-color key.
20 to 29: Use data from second
preceding same-color
key.
30 to 39: Use emergency table.
