1.1.1 Definitions
Frequency converter:
Coast
The motor shaft is in free mode. No torque on motor.
I
MAX
The maximum output current.
I
N
The rated output current supplied by the frequency
converter.
U
MAX
The maximum output voltage.
Input:
Control command
Start and stop the connected motor using the LCP and the
digital inputs.
Functions are divided into two groups.
Functions in group 1 have higher priority than functions in
group 2.
Group 1 Reset, Coasting stop, Reset and Coasting stop, Quick-
stop, DC braking, Stop and the "Off" key.
Group 2 Start, Pulse start, Reversing, Start reversing, Jog and
Freeze output
Table 1.1 Control Command Functions
Motor:
f
JOG
The motor frequency when the jog function is activated
(via digital terminals).
f
M
Motor frequency. Output from the frequency converter.
Output frequency is related to the shaft speed on motor
depending on number of poles and slip frequency.
f
MAX
The maximum output frequency the frequency converter
applies on its output. The maximum output frequency is
set in limit par. 4-12, 4-13 and 4-19.
f
MIN
The minimum motor frequency from frequency converter.
Default 0 Hz.
f
M,N
The rated motor frequency (nameplate data).
I
M
The motor current.
I
M,N
The rated motor current (nameplate data).
n
M,N
The rated motor speed (nameplate data).
n
s
Synchronous motor speed
ns =
2 × par. 1 − 23 × 60 s
par. 1 − 39
P
M,N
The rated motor power (nameplate data).
T
M,N
The rated torque (motor).
U
M
The instantaneous motor voltage.
