wards/backwards, press the
<Start> key)

P-13 Error log The 4 most recent errors are
logged No error The last 4 errors are saved in chronological order.
The most recent error is displayed first. You can
view the saved errors by pressing the <Up/Down>
key. See section "Error codes" (page 40).
P-14 Advanced menu
access code 0 – 9999 0 "101" (standard) for advanced menu access.
Change the code in
P-37 to prevent unauthorized
access to the advanced parameter set.
1) 60 Hz (American variant only)
2) 460 V (American variant only)
Parameter Description Range Default Explanation
P-15 Binary input func-
tion setting 0 – 12 0 Specifies the functions of the binary inputs. See
section "P-15 Functions of the binary inputs"
(page 48).
P-16 Analog input V /
mA 0 – 10 V, b 0 – 10 V, 0 – 20 mA
t 4 – 20 mA, r 4 – 20 mA
t 20 – 4 mA, r 20 – 4 mA 0 – 10 V Configures the format of the analog input.
0 – 10 V: Unipolar mode (voltage input)
b 0 – 10 V: Bipolar mode (voltage input)
• For bipolar input signals
• 50% offset with P-39
• 200% scaling in P-35 results in ± P-01
0 – 20 mA: Unipolar mode (current input)
4 – 20 mA: Unipolar mode (current input)
20 – 4 mA: Unipolar return current mode
"t" = Inverter switches off if signal is revoked when
inverter is enabled.
"r" indicates that the inverter moves along the ramp
to the speed set in
P-20 .
P-17 PWM 2 – 16 kHz 4 / 8 kHz PWM setting.
A higher switching frequency means less motor
noise, but also higher losses in the output stage.
P-18 User relay output
selection 0 Inverter is enabled 1
(inverter
ok) User relay settings. The threshold level is defined
in
P-19 .
Deactivated: Contacts open
Activated: Contact closed
1 Inverter ok (no error)
2 Motor at setpoint speed
3 Inverter is not enabled
4 Motor speed ≥ limit value
5 Motor current ≥ limit value
6 Motor speed < limit value
7 Motor current < limit value
P-19 Relay threshold
level 0 – 200% of maximum speed P-01
or nominal motor current P-08
100% Specifies the limit value for P-18 and P-25 .
