Parameters
11.2 Parameter list
Parameter Name
Note: The value of -200 indicates that there is no measuring signal.
r0037[0]: Maximum value of the inverter temperatures (r0037[5...10]).
•
r0037[1]: Maximum value of the depletion layer temperatures (r0037[13...18]).
•
r0037[2]: Maximum value of the rectifier temperatures (r0037[11...12]).
•
The maximum value is the temperature of the hottest inverter, depletion layer, or rectifier.
r0079[0...1] Torque setpoint total
Description: Displays and connector output for the torque setpoint at the output of the speed controller
(before clock cycle interpolation).
Index:
[0]: Unsmoothed
•
[1]: Smoothed
•
r0296 DC link voltage undervoltage threshold
Description: Threshold to detect a DC link undervoltage.
If the DC link voltage falls below this threshold, the drive unit is tripped due to a DC link undervoltage
condition.
Note: The value depends on the device type and the selected device rated voltage.
r0297 DC link voltage overvoltage threshold
Description: If the DC link voltage exceeds the threshold specified here, the drive unit is tripped due to
DC link overvoltage.
Dependency: Refer to F30002.
r0311 Rated motor speed
Description: Displays the rated motor speed (rating plate).
r0333 Rated motor torque
Description: Displays the rated motor torque.
IEC drive: unit Nm
NEMA drive: unit lbf ft
r0482[0...2] Encoder actual position value Gn_XIST1
Description: Displays the encoder actual position value Gn_XIST1.
Index:
[0]: Encoder 1
•
[1]: Encoder 2
•
[2]: Reserved
•
Note:
In this value, the measuring gear is only taken into account when the position tracking is activated.
•
The update time for the position control (EPOS) corresponds to the position controller clock cycle.
•
The update time in isochronous operation corresponds to the bus cycle time.
•
The update time in isochronous operation and with position control (EPOS) corresponds to the
•
position controller clock cycle.
The update time in non-isochronous operation or without position control (EPOS) comprises the
•
following:
–
–
–
298
Update time = 4 * least common multiple (LCM) of all current controller clock cycles in the drive
group (infeed + drives). The minimum update time is 1 ms.
Example 1: infeed, servo
Update time = 4 * LCM(250 μs, 125 μs) = 4 * 250 μs = 1 ms
Example 2: infeed, servo, vector
Update time = 4 * LCM(250 μs, 125 μs, 500 μs) = 4 * 500 μs = 2 ms
