14.4.6.15 Message word
Overview
The message word (MELDW) signals the converter status to the higher-level control system.
Description of function
Message word (MELDW)
Converter → Control
Bit Status Explanation
00 0 = Ramp-function generator active The motor is presently accelerat‐
ing or braking.
1 = Ramp-up/ramp-down completed Speed setpoint and actual speed
are the same.
01 1 = Torque utilization[%] < torque threshold value2 (p2194) ---
02 1 = |n_actt| <speed threshold value3 (p2161) ---
03 1 = |n_act| speed threshold value2 (p2155) ---
04 1 = Vdc_min controller active ---
05 Variable signaling function 1 output signal ---
06 1 = No motor overtemperature alarm The motor temperature is within
the permissible range.
07 1 = No alarm power unit thermal overload The converter temperature is
within the permissible range.
08 1 = Speed setpoint - actual value deviation within tolerance
t_on
Speed setpoint and actual speed
are within the permissible toler‐
ance p2163.

Reserved
11 1 = Controller enable The speed controller is enabled.
12 1 = Drive ready The converter is ready to start.
13 1 = pulses enabled The motor is switched on.
14 Variable signaling function 2 output signal ---
15 Variable signaling function 3 output signal ---
