®
(VLT 24 V DC Supply MCB 107) and the
main power to the unit is not detected.
[2] Drive ready The frequency converter is ready for
operation and applies a supply signal on
the control board.
[3] Drive ready/ The frequency converter is ready for
remote control operation and is in Auto On mode.
[4] Enable/no Ready for operation. No start or stop
warning command has been given (start/disable).
No warnings are active.
[5] VLT running The motor runs and shaft torque is
present.
[6] Running/no The output speed is higher than the
warning speed set in parameter 1-81 Min Speed for
Function at Stop [RPM]. The motor runs
and there are no warnings.
[7] Run in Motor runs within the programmed
range/no current and speed ranges set in
warning parameter 4-50 Warning Current Low to
parameter 4-53 Warning Speed High. There
are no warnings.
[8] Run on Motor runs at reference speed. No
reference/no warnings.
warning
[9] Alarm An alarm activates the output. There are
no warnings.
[10] Alarm or An alarm or a warning activates the
warning output.
[11] At torque limit The torque limit set in
parameter 4-16 Torque Limit Motor Mode
or parameter 4-17 Torque Limit Generator
Mode has been exceeded.
[12] Out of current The motor current is outside the range
range set in parameter 4-18 Current Limit.
[13] Below current, Motor current is lower than set in
low parameter 4-50 Warning Current Low.
[14] Above current, Motor current is higher than set in
high parameter 4-51 Warning Current High.
[15] Out of range Output frequency is outside the
frequency range set in
parameter 4-52 Warning Speed Low and
parameter 4-53 Warning Speed High.
[16] Below speed, Output speed is lower than the setting in
low parameter 4-52 Warning Speed Low.
[17] Above speed, Output speed is higher than the setting
high in parameter 4-53 Warning Speed High.
[18] Out of Feedback is outside the range set in
feedback range parameter 4-56 Warning Feedback Low and
parameter 4-57 Warning Feedback High.
[19] Below Feedback is below the limit set in
feedback low parameter 4-56 Warning Feedback Low.
[20] Above Feedback is above the limit set in
feedback high parameter 4-57 Warning Feedback High.
[21] Thermal The thermal warning turns on when the
warning temperature exceeds the limit in the
MG33ML02

motor, the frequency converter, the brake
resistor, or the thermistor.
Frequency converter is ready for
operation, and there is no overtem-
perature warning.
Frequency converter is ready for
operation and is in Auto On mode. There
is no overtemperature warning.
Frequency converter is ready for
operation and the mains voltage is within
the specified voltage range (see the
section General Specifications in the
frequency converter design guide).
The motor runs (or is ready to run)
clockwise when logic = 0 and counter-
clockwise when logic = 1. The output
changes when the reversing signal is
applied.
Active communication (no timeout) via
the serial communication port.
Use in performing a coast stop and in
torque limit condition. If the frequency
converter has received a stop signal and
is at the torque limit, the signal is logic 0.
Brake is active and there are no warnings.
Brake is ready for operation and there are
no faults.
Output is logic 1 when the brake IGBT is
short-circuited. Use this function to
protect the frequency converter if there is
a fault on the brake modules. To cut out
the main voltage from the frequency
converter, use the output/relay.
Relay is activated when [0] Control word is
selected in parameter group 8-**
Communications and Options.
Enables control of an external mechanical
brake. For more information on
mechanical brake control, refer to the
frequency converter design guide.
Indicates that the Safe Torque Off on
terminal 37 is activated.
Active when the actual speed is outside
settings in parameter 4-52 Warning Speed
Low to parameter 4-55 Warning Reference
High.
Active when actual speed is below speed
reference setting.
Active when actual speed is above speed
reference setting.
