The user defined format sets the attributes (or units) that are enabled when P8.03 > 0. These
settings allow the user to define a display field according to specific system processes. The
frequency command signal will be scaled according to P0.04 (Max Output Freq) and P8.03 (User
Coefficient Max)
Example:
• P004 Max Output Freq = 60 Hz
• P800 User Display = 30 (User Defined)
• P802 User Defined Format = 0072h (unit = ppm, two decimal places)
• P803 User Defined Max = 11500
An analog frequency setting of 50% will result a 30Hz setting, but the keypad will display the
user format 57.50ppm (50% x 115.00ppm). Likewise a commanded frequency input value of
100.00ppm will result in an output frequency of 52.17Hz = (100ppm/115ppm) x 60Hz.
Note: Running in forward or reverse will display a positive value.
P8.03 User Defined Max
Range/Units (Format: 16-bit unsigned)
0: Disable
0~65535 (when P802 set to no decimal place)
00~65535 (when P802 set to 1 decimal place)
000~65535 (when P802 set to 2 decimal place)
0000~65535 (when P802 set to 3 decimal place)
User defined is enabled when P8.03 is not 0. The setting of P8.03 is linearly scaled to P0.04 (Max
Output Frequency).
See example in P8.02 for further information.
