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
