Instruction manual V 2.3
21
PWM 230 - PWM 400 - PWM 400/7.5
Instruction manual
The name of the parameter appears at first for a second. Thereafter the hundreds are shown and, finally, the
tens and the units are shown. The Hundreds are represented on the right digit, while the left one is off;
thereafter the left digit represents the tens while the right digit represents the units. Three-digit numbers are
completely displayed for three times in 5 seconds, and then the two-letters parameter name will be displayed
for one second. During value modification only tens and units of three-digit parameter values are shown.
After value modification has completed, parameter values are displayed on three digits again.
For quantities that contain a decimal digit the digit is displayed for values up to 9,9, while when this value is
exceeded only tens and units are displayed.
WARNING
:
When the PWM is configured for connection to another PWM or to a "Da Vinci" controller
board (see sections 5.1.2.6, 5.1.2.6.1 and 5.1.2.6.2) but the communication doesn't work,
the display blinks when the "Go" or "Sb" status codes are displayed.
