r0056.0...15 CO/BO: Status of
motor control
- - - - - U16 3
Displays status of motor control (in bit format), which can be used to diagnose converter status.
Bit Signal name 1 signal 0 signal
00 Init. control finished Yes No
01 Motor demagnetizing finished Yes No
02 Pulses enabled Yes No
03 Voltage soft start select Yes No
04 Motor excitation finished Yes No
05 Starting boost active Yes No
06 Acceleration boost active Yes No
07 Frequency is negative Yes No
08 Field weakening active Yes No
09 Volts setpoint limited Yes No
10 Slip frequency limited Yes No
11 f_out > f_max Freq. limited Yes No
12 Phase reversal selected Yes No
13 Imax controller active/torque limit reached Yes No
14 Vdc_max controller active Yes No
15 KIB (Vdc_min control) active Yes No
Notice: The I-max controller (r0056 bit 13) will be activated when the actual output current (r0027) exceeds the
current limit in r0067.
r0066 CO: Actual output
frequency [Hz]
- - - - - Float 3
Displays actual output frequency in Hz. This value is available filtered (r0024) and unfiltered (r0066).
Note: The output frequency is limited by the values entered in P1080 (minimum frequency) and P1082 (maxi-
mum frequency).
r0067 CO: Actual output
current limit [A]
- - - P2002 - Float 3
Displays valid maximum output current of converter.
r0067 is influenced/determined by the following factors:
•
Converter application P0205
• Rated motor current P0305
•
Motor overload factor P0640
• Motor protection in dependency of P0610
•
r0067 is less than or equal to maximum converter current r0209
• Converter protection in dependency of P0290
Note: A reduction of r0067 may indicate a converter overload or a motor overload.
r0068 CO: Output current [A] - - - P2002 - Float 3
Displays unfiltered [rms] value of motor current. This value is available filtered (r0027) and unfiltered
(r0068).
Note: Used for process control purposes (in contrast to r0027, which is filtered and is used to display the value
through USS).
