Motor Temp. Operation Mode. 570 - monitoring the motor temperature protects the
drive system. Connect a suitable sensor to digital input S6IND.
0 - thermo-contact switched off
1 - thermo-contact warning message
2 - thermo-contact error switch-off
3 - Thermo-contact error switch-off after 1 min
4 - Thermo-contact error switch-off after 5 min
Setting:
5 - Thermo-contact error switch-off after 10 min
Operation Mode 645 (for synchronization) - synchronization to a rotating drive is
useful in some applications such as pumps and fans or after acknowledgement of an
error switch-off. If synchronization to the motor speed is not possible, the function is
quit and a fault message is issued.
0 - switched off
Setting:
10 - synchronization switched on, quick synchronization
Operation Mode 651 - automatic startup of the drive is permissible only in
accordance with VDE 0113 (Section 5.4, 5.5), VDE 0100 Part 227 and the national
regulations. Make sure that automatic startup does not result in any dangerous
situation.
0 - switched off, control signal at S1IND, S2IND or S3IND
Setting:
1 - automatic startup, control signal at S1IND, S2IND or S3IND
Operation Mode 670 - the DC link voltage, which increases due to generatoric
operation and/or deceleration operations, is limited by means of the voltage
controller or an external braking resistor in order to avoid an error switch-off due to
overvoltage.
0 - switched off, limited by connected brake resistor
Setting:
1 - overvoltage controller, controlled deceleration ramps
The following parameters are displayed in addition to the basic parameters in
configuration 410.
Integral Time 1 722 - the control behavior of configuration 410 is to be adapted,
depending on the mechanical moment of inertia, via the integral time of the speed
controller. The lower the value is, the more dynamic the behavior. The increase in
inherent instability of the system is proportional to the reduction of the integral time.
Setting: 0 ... 60000 ms
Current Limit 728 - the speed and torque can be controlled separately in
configuration 410. The torque is limited to the rated torque if the current limit is the
same as the
Rated Current 371 of the motor.
