• Analog Outputs
– Meter Indication
– Terminal 42 and 45 set to AO or DO
– If using 0-Fmax 0-20mA, meter trim is P 202.
– New software – meter trim – use P 357 – 360.
Analog Outputs
The current meter shown above has its positive terminal wired to terminal 42 of the
drive and the negative terminal wired to terminal 39. Terminal 45 can also be used for meter
indication. Parameter 319 sets the display for terminal 42 (default is 0 to Imax, current) and
parameter 321 sets the display for terminal 45 (default is 0 to Fmax, frequency). Each AO
option has 3 output selections, 0-20mA; 4-20mA or 0-32,000 pulses. If 0-Fmax is used for
terminal 45, the meter can be trimmed by adjusting parameter 202. By default parameter
202 is set to 132Hz, which means that the output reaches 20mA when the drive frequency
reaches 132Hz. If parameter 202 is changed to 60Hz, the meter reaches 20mA when the
drive frequency reaches 60Hz.
In the latest software revisions, parameters 357 sets the output minimum scaling on
terminal 42 and parameter 358 sets the output maximum scaling. Parameter 359 sets the
output minimum scaling on terminal 45 and parameter 360 sets the output maximum scaling.
