Speed Control Configuration With I/O Using Default - Danfoss iC2 Application Manual

Application Guide | iC2-Micro Frequency Converters
2.
To test motor operation, start the motor at low speed (100–200 RPM). If the motor does not turn, check installation, general
parameter configurations, and motor data.
3.
Perform parking operation by setting P 5.6.14 Sync. Motor Parking Current % and P 5.6.13 Sync. Motor Parking Time. The
factory setting values of the parameters can be adjusted and increased for applications with high inertia. Start the motor at
nominal speed. If the application does not run well, check the VVC+ PM settings. The following table shows recommendations
in different applications.
Table 13: Recommendations in Different Applications
Application
Low inertia applications ILoad/IMotor<5
Medium inertia applications 50>ILoad/IMotor>5
High inertia applications ILoad/IMotor>50
High load at low speed <30% (rated speed)
If the motor starts oscillating at a certain speed, increase P 4.4.4.7 Damping Gain. Increase the value in small steps. Starting
torque can be adjusted in P 4.4.4.14 Min. Current at Low Speed. 100% provides nominal torque as starting torque.

Settings
• Increase the value for P 4.4.4.10 Voltage filter time const.
by factor 5–10.
• Reduce the value for P 4.4.4.7 Damping Gain.
• Reduce the value (<100%) for P 4.4.4.14 Min. Current at
Low Speed.
Keep calculated values.
Increase the values for P 4.4.4.7 Damping Gain, P 4.4.4.9 Low
Speed Filter Time Const., and P 4.4.4.8 High Speed Filter Time
Const.
Increase the value for P 4.4.4.10 Voltage filter time const.
Increase the value for P 4.4.4.14 Min. Current at Low Speed
(>100% for longer time can overheat the motor).
