Introduction

1.5.2 Input

Control command
Start and stop the connected motor with keypad and
digital inputs.
Functions are divided into 2 groups.
Functions in group 1 have higher priority than functions in
group 2.
Group 1 Reset, coast stop, reset, and coast stop, quick stop,
DC brake, stop, the [OFF] key.
Group 2 Start, pulse start, reversing, start reversing, jog,
freeze output.

DRIVE
The efficiency of the frequency converter is defined as the
ratio between the power output and the power input.
Start-disable command

Advanced Vector Control
If compared with standard voltage/frequency ratio control,
advanced vector control improves the dynamics and the
stability, both when the speed reference is changed and in
relation to the load torque.
Analog reference
A signal transmitted to the analog inputs 53 or 54 (voltage
or current).
Binary reference
A signal transmitted to the serial communication port.
Preset reference
A defined preset reference to be set from -100% to +100%
of the reference range. Selection of 8 preset references via
the digital terminals.
Pulse reference
A pulse frequency signal transmitted to the digital inputs
(terminal 29 or 33).
Ref
MAX
Determines the relationship between the reference input at
100% full scale value (typically 10 V, 20 mA) and the
resulting reference. The maximum reference value is set in
parameter F-53 Maximum Reference.
