5. SYSTEM PARAMETERS
Parameter
Number
2
P0614
Motor I
t overload warning level
2
The motor I
t calculation estimates the duration for which the motor can be overloaded
without overheating. When the maximum allowed period has been reached the motor I
calculation is 100% (see r0034). This parameter defines the calculated I
which a warning (A0511) is generated.
Note:
A motor over-temperature trip (F0011) is produced at 110% of this level.
P0640
Motor overload factor
Defines instantaneous Motor overload factor as a % of the nominal motor current. This
value is limited to 150% of nominal inverter current (r0207) or to 400% of the motor current
(whichever is the lower).
P0700
Selection of command source
Parameter for selecting the digital command source. When the parameter is changed, all
digital input parameters will be set to reasonable values.
Possible Settings
0
"Factory default setting"
1
"keypad" (BOP/AOP)
2
"Terminal"
4
"USS1 on BOP-Link" (RS-232)
5
"USS2 on Comm-Link" (RS-485)
6
"PROFIBUS / Fieldbus on Comm-Link"
Note:
Changing this parameter resets the settings to default on the item selected e.g. if you
change from setting 1 to setting 2, all digital inputs will now have default settings
P0701

4 OFF3 – Quick ramp down (P1135 defines OFF3 ramp-down time)
9 Fault acknowledge
10 JOG right
11 JOG left
12 Reverse
13 Increase frequency (Main/additional setpoint=Keypad (P1000))
14 Decrease frequency (Main or additional setpoint = Keypad)
15 Fixed frequency 1 (see P1001)
16 Fixed frequency 1 + ON (see P1001)
17 Fixed frequencies 1 to 7 (Binary Coded) (see P1001)
25 DC brake enable (see P1230 to P1233)
29 External trip
33 Disable additional setpoint (defined in P1000)
99 Enable BICO parameterization – for expert use only
Can only be reset via P0700 or P3900 = 1, 2 or factory setting P0970 = 1
