60° asynchronous vector modulation (parameter 14-00 Switching Pattern).
A
The actual position from an encoder, or a value that the motor control cal-
culates in open loop. The drive uses the actual position as feedback for po-
sition PI.
A signal transmitted to the analog inputs 53 or 54 (voltage or current).
The analog inputs are used for controlling various functions of the drive.
There are 2 types of analog inputs:
Current input, 0–20 mA, and 4–20 mA
Voltage input, -10 V DC to +10 V DC.
The analog outputs can supply a signal of 0–20 mA, 4–20 mA.
Automatic motor adaptation, AMA
AMA algorithm determines the electrical parameters for the connected mo-
tor at standstill.
B
A BDM is a drive module which consists of a power converter module and a
control and regulating device for speed, torque, current, or voltage.
A signal transmitted to the serial communication port.
The brake resistor is a module capable of absorbing the brake power gener-
ated in regenerative braking. This regenerative brake power increases the
DC-link voltage and a brake chopper ensures that the power is transmitted
to the brake resistor.
C
Condition Based Monitoring monitors the machine condition and perform-
ance when the drive is in service and detects mechanical, motor, or applica-
tion failures in advance. Corrective actions can be performed before the
process or application is impacted.
A CDM is a drive system without the motor and without the measuring sen-
sors, which are mechanically connected to the motor shaft. The drive sys-
tem consists of, but is not restricted to, the BDM and extensions, such as the
feed module and auxiliary equipment.
