The following resistors are available for use with the MTX micro:
● HLR01.1N-0470-N11R7-A-007-NNNN (R911305932)
● HLR01.1N-02K0-N15R0-A-007-NNNN (R911306870)
● HLR01.1N-05K0-N15R0-A-007-NNNN (R911306881)
Technical data are specified in the annex
● It is not allowed to operate the HCQ02 without any external
resistor.
● The line cross-section required for connecting the external
resistor is 6 mm².
● Only use shielded or twisted lines for connecting the external
resistor.
● The lines must be designed for a load of 630 V, 32 A DC
peak, 15 A DC effective.
● The maximum line length is 5 m.
● It must be ensured that the line voltage is turned off after the
drives have stopped if there is a DC bus short-circuit (24-V
drop at input X19.1 (DC bus voltage)). Otherwise, the exter‐
nal resistor may be destroyed. This is ensured by the circuit
examples shown herein.
24-V control voltage supply
When dimensioning the control voltage supply for the MTX micro, please ob‐
serve the power consumption figures of the following components:
● Voltage supply of the HCQ/HCT device
● onboard digital inputs and outputs
● Option modules
● Actuating the engine brakes
● HMI control panel
