2.2 List of parameters
Note: For bit 00:
State to display the single initialization after POWER ON.
For bit 01:
State in which the automatic restart function waits for faults (initial state).
For bit 02:
General display that a fault has been identified and that the restart or acknowledgment has been initiated.
For bit 03:
Displays the acknowledge command within the "acknowledge alarms" state (bit 4 = 1). For bit 5 = 1 or bit 6 = 1, the
acknowledge command is continually displayed.
For bit 04:
State in which the faults that are present are acknowledged. The state is exited again after successful
acknowledgment. A change is only made into the next state if it is signaled that a fault is no longer present after an
acknowledgment command (bit 3 = 1).
For bit 05:
State in which the drive is automatically switched on (only for p1210 = 4, 6).
For bit 06:
State in which the system waits after having been switched on, to the end of the start attempt (to the end of the
magnetizing process).
For p1210 = 1, this signal is directly set after the faults have been successfully acknowledged.
For bit 07:
State which is assumed after a fault occurs within the automatic restart function. This is only reset after
acknowledging the fault and withdrawing the switch-on command.
For bit 10:
When the automatic restart function is active, r1214.7 is displayed, otherwise the active fault r2139.3.
The bit is set if the automatic restart can no longer acknowledge a fault, and cancels with fault F07320.
For bits 12 ... 15:
Actual state of the start counter (binary coded).
For bit 04 in addition:
For p1210 = 26, the system waits in this state until the switch-on command is available.
Description: Sets the speed threshold for the standstill identification.
Acts on the actual value and setpoint monitoring.
When braking with OFF1 or OFF3, when the threshold is undershot, standstill is identified.
Dependency: Refer to: p1227
Caution: The following applies for encoderless speed control:
If p1226 is set to values under approx. 1 % of the rated motor speed, then the model switchover limits of the vector
control must be increased in order to guarantee reliable shutdown (see p1755, p1750.7).
Notice: For reasons relating to the compatibility to earlier firmware versions, a parameter value of zero in indices 1 to 31 is
overwritten with the parameter value in index 0 when the Control Unit boots.
Note: Standstill is identified in the following cases:
- the speed actual value falls below the speed threshold in p1226 and the time started after this in p1228 has expired.
- the speed setpoint falls below the speed threshold in p1226 and the time started after this in p1227 has expired.
The actual value sensing is subject to measuring noise. For this reason, standstill cannot be detected if the speed
threshold is too low.
