Application Guide | iC2-Micro Frequency Converters
2.2.7
Motor Phase Switch
If motor phase cables have been installed in an incorrect order during installation, the rotation direction can be changed. This eliminates
the need to change the order of motor phases.
2.2.8
Inching with Jogging Modes
The frequency converter has predefined speed settings for use during commissioning, maintenance, or service. The jogging-mode
operation is set at preset speed.
2.2.9
Frequency Bypass
Specific motor frequencies can be bypassed during operation. The feature helps to minimize and avoid mechanical resonance of the
machine, limiting vibration and noise of the system.
2.2.10
Automatic Restart
In case of a minor fault and trip, the drive can do an automatic restart, eliminating a manual reset of the drive. This enhances automated
operation in remotely controlled systems. Make sure that dangerous situations cannot occur when using automatic restart.
2.2.11
Flying Start
Flying start enables the drive to synchronize to a freely spinning motor, before taking control of the motor. Taking over control of
the motor at the actual speed minimizes mechanical stress to the system. For example, the feature is relevant in fan and centrifuge
applications.
2.2.12
Mains Dropout
In case of mains dropout, where the drive cannot continue operation, it is possible to select predefined actions, for example trip, coast, or
performing a controlled ramp down.
2.2.13
Kinetic Backup
Kinetic backup enables the drive to remain in control if there is sufficient energy in the system, for example, as inertia or when lowering a
load. This allows a controlled stop of the machine.
2.2.14
Resonance Damping
High-frequency motor resonance noise can be eliminated through the use of resonance damping. Both automatic and manually
selected frequency damping are available.
2.2.15
Mechanical Brake Control
In applications like simple hoists, palletizers, stereoscopic warehouse, or downhill conveyors, a mechanical brake is used to keep the load
at standstill, when the motor is not controlled by the drive or when power is turned off.
The mechanical brake control feature ensures a smooth transition between the mechanical brake and motor holding the load, by
controlling the activation and deactivation of the mechanical brake.
2.2.16
Controllers
The drive has 3 different controllers providing optimized control of the actual application. The controllers cover:
l
Process control
l
Speed control open loop
l
Torque control open loop
