Note: If P051 or P052 = 6 or 18 while P053 or P054 or P055 = 17
then the setpoints are added.
Examples:
0 = 12.5 ms
0 - 2
1 = 7.5 ms
[0]
2 = 2.5 ms
0.0-650.0 Time interval between expected 'Watchdog kicks' or if this time interval should
lapse without a pulse on one of the digital inputs, an F057 trip will occur.
[1.0]
(See P051 to P055 and P356)
0 - 13
Sets the relay function, output RL1 (terminals 18,19 and 20)

Value Relay function
0 No function assigned (relay not active)
1 Inverter is running
2 Inverter frequency 0.0 Hz
3 Motor running direction right
4 External brake on (see parameters P063/P064)
5 Inverter frequency greater than minimum frequency
6 Fault indication
7 Inverter frequency greater than or equal to setpoint
8 Warning active
9 Output current greater than or equal to P065
10 Motor current limit (warning)
11 Motor over temperature (warning)
12 PID closed loop motor LOW speed limit
13 PID closed loop motor HIGH speed limit
Inverter switches off (see parameter P930 and P140 to P143 and section 7).
1
2
Inverter does not trip(see parameter P931).
3 'Active low' = relay OFF/ de-energised or 'Active high' = relay ON/
energised
Note: If the external brake function is used (P061 or P062 = 4)
and additional slip compensation is used (P071¹ 0),
minimum frequency must be less than 5 Hz (P012 < 5.00),
otherwise the inverter may not switch off.
Warning:Relay operation is not defined during parameter changes and
may change unpredictably.
Ensure any equipment connected to the relays will remain safe
if the relays change state during parameterisation.
0 - 13 Sets the relay function, output RL2 (terminals 21and 22) (refer to the table in
[8] P061).

(1) P053 = 17, P054 = 17, P055 = 17:
All 8 fixed frequencies are available
e.g. DIN3 = 1, DIN4 = 1, DIN5 = 0 Þ FF3 (P043)
(2) P053 ¹ 17, P054 = 17, P055 = 17:
DIN3 is fixed at zero (only FF5 to FF8 available)
e.g. DIN4 = 1, DIN5 = 0 Þ FF7 (P048)
