10.2 Definitions
10.2.1 AC Drive
Coast
The motor shaft is in free mode. No torque on the motor.
I
VLT,MAX
Maximum output current.
I
VLT,N
Rated output current supplied by the drive.
U
VLT,MAX
Maximum output voltage.
10.2.2 Input
Control commands
Start and stop the connected motor with LCP and digital inputs.
Functions are divided into 2 groups.
Functions in group 1 have higher priority than functions in group 2.
Table 91: Function Groups
Group 1
Reset, coast stop, reset and coast stop, quick stop, DC brake, stop, and [Off].
Group 2
Start, pulse start, reversing, start reversing, jog, and freeze output.
10.2.3 Motor
