This parameter sets the carrier frequency of the Pulse-Width-Modulation wave form sup-
plied to the motor. Low carrier frequencies provide better low end torque but produce some
audible noise from the motor. Higher carrier frequencies produce less audible noise but
cause more heating in the inverter. The ACP 3000 is rated to produce continuous full load
current at rated ambient temperatures when parameter
83-PWM
is set to carrier frequen-
cies of 4, 6 or 8 kHz.
NOTE:
12 and 16 kHz levels automatically shift to 6 and 8 kHz respectively in the event of low out-
put voltage or if derating is exceeded. In Autoselect, the inverter runs at 16 kHz then auto-
matically shifts to 8 kHz in the event of low output voltage, if the derating is exceeded, or if
inverter temperature exceeds 70 °C. If inverter temperature further exceeds 85 °C, the in-
verter shifts to 4 kHz. Upshifting occurs if the temperatures drop below these thresholds.

This parameter determines information displayed on the LCD readout during Run opera-
tion. The display will always show frequency in the Stop mode and while the speed is being
set.

DESCRIPTION
0
Line Start Lock-out. If maintained contact run operators are used, they must be
opened and then re-closed for the drive to start after application of AC power.
STOP key active as Emergency, Coast-To-Stop, for
21-MODE
= 2–9. To reset
an E-Stop, press the STOP key again. No Stop with signal loss at connector J22.
1
Auto-Start. Will start on power-up if direction connection is made at the control
terminals after application of AC power. STOP key active as Emergency, Coast-
To-Stop, for
21-MODE
= 2–9. To reset an E-Stop, press the STOP key again. No
Stop with signal loss at connector J22.
2
Start into a rotating motor with Line Start Lock-out. (See Note on starting into
a rotating motor). STOP key active as Emergency, Coast-To-Stop, for
21-MODE
= 2–9. To reset an E-Stop, press the STOP key again. No Stop with signal loss
at connector J22.
3
Start into a rotating motor with Auto-Start. STOP key active as Emergency,
Coast-To-Stop, for
21-MODE
= 2–9. To reset an E-Stop, press the STOP key
again. No Stop with signal loss at connector J22.
4–7
Same Start functions as Data Codes 1–3, but Keypad STOP key will be disabled
if Start/Stop is defined as terminals by
21-MODE
. No Stop with signal loss at con-
nector J22.
8–11
Same Start functions as Data Codes 1–3, but drive will initiate a Stop function
(as defined by
41-RSEL
) if a remote device signal is sensed at connector J22
and then lost.
