P0626[0...2]
Overtemperature stator iron
[°C]
20.0 - 200.0 50.0 U, T - DDS Float 4
Overtemperature of stator iron.
Note: Temperature rises are valid for sinusoidal operations (line supply temperature rises). Temperature rises
due to converter operation (modulation losses) and output filter are also considered.
P0627[0...2] Overtemperature stator
winding [°C]
20.0 - 200.0 80.0 U, T - DDS Float 4
Overtemperature of the stator winding. It is only allowed to change the value when the motor is cold. A
motor identification has to be made after changing the value.
Note: See P0626
P0628[0...2] Overtemperature rotor
winding [°C]
20.0 - 200.0 100.0 U, T - DDS Float 4
Overtemperature of the rotor winding.
Note: See P0626
r0630[0...2] CO: Motor model sur-
rounding temp. [°C]
- - - - DDS Float 4
Displays the surrounding temperature of the motor mass model.
r0631[0...2] CO: Stator iron tempera-
ture [°C]
- - - - DDS Float 4
Displays the iron temperature of the motor mass model.
r0632[0...2] CO: Stator winding tem-
perature [°C]
- - - - DDS Float 4
Displays the stator winding temperature of the motor mass model.
r0633[0...2] CO: Rotor winding tem-
perature [°C]
- - - - DDS Float 4
Displays the rotor winding temperature of the motor mass model.
P0640[0...2]
Motor overload factor [%]
10.0 - 400.0 150.0 C, U, T - DDS Float 2
Defines motor overload current limit relative to P0305 (rated motor current).
Dependency: Limited to maximum converter current or to 400 % of rated motor current (P0305), whichever is the lower.
P0640_max = (min(r0209, 4 * P0305)/P0305) * 100
Note: Changes to P0640 will be effective only after the next off state.
P0700[0...2] Selection of command
source
0 - 5 1 C, T - CDS U16 1
Selects digital command source.
0 Factory default setting
1 Operator panel (keypad)
2 Terminal
5 USS/MODBUS on RS485
Dependency: Changing this parameter sets (to default) all settings on item selected. These are the following parame-
ters: P0701, ... (function of digital input), P0840, P0842, P0844, P0845, P0848, P0849, P0852, P1020,
P1021, P1022, P1023, P1035, P1036, P1055, P1056, P1074, P1110, P1113, P1124, P1140, P1141,
P1142, P1230, P2103, P2104, P2106, P2200, P2220, P2221, P2222, P2223, P2235, P2236
Caution: Be aware, by changing of P0700 all BI parameters are reset to the default value.
Note: RS485 also supports MODBUS protocol as well as USS. All USS options on RS485 are also applicable to
MODBUS.
If P0700 = 0, the values of the following parameters relevant to the digital input function will be restricted
to their defaults: P0701, P0702, P0703, P0704, P0712 and P0713.
