Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Refer to: p1335
Note: The value is only determined for operating modes with Economic (p1300 = 4, 7).
Description: Sets the maximum output frequency for resonance damping for U/f control.
Resonance damping is inactive above this output frequency.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1338, p1339
Note: For p1349 = 0, the changeover limit is automatically set to 95 % of the rated motor frequency - however, to a max. of
45 Hz.
Description: Sets whether the voltage is continuously increased during the magnetizing phase (p1350 = 1, On) or whether it jumps
directly to the voltage boost (p1350 = 0, Off).
Value: 0: OFF
1: ON
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: The settings for this parameter have the following advantages and disadvantages:
0 = off (jump directly to voltage boost)
Advantage: Flux is established quickly -> torque is quickly available
Disadvantage: The motor can move while it is being magnetized
1 = on (voltage is continually established)
Advantage: The motor is unlikely to rotate
Disadvantage: The flux is established slower -> torque is available later
Description: Sets the frequency setting value at the slip compensation output for starting up with motor holding brake.
Dependency: When setting p1351 > 0, then slip compensation is automatically activated (p1335 = 100 %).
Refer to: p1302, p1352
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: Connected with p1352 a value of 100% corresponds to the motor rated slip (r0330).
