8.2.11 Dedicated I/O For Input Protection (NXGpro)
Dedicated I/O for Input Protection (NXGpro)
The drive NXGpro software controls the I/O involved with input protection. No intervention is
required for activating this usage other than selecting one of these cell types. For drives other
than SINAMICS PERFECT HARMONY GH180 6SR4, and 6SR3, the parameter "Dedicated
Input Protect" (ID 7018) can be used to enable the same protection if the system I/O board is
installed and the inputs and outputs are wired properly. When dedicated I/O is used, the
parameter "Drive Has Input Breaker" must be set to "Yes" or the system will not allow the
breaker to close. The SOP flags that would normally be associated with these inputs and
outputs are disabled, and have no effect when dedicated I/O is enabled.
These are the inputs and outputs dedicated in this manner to the input protection algorithm.
● M1_DOUT - The M1 permissive allows the circuit to close M1 (to be completed by the
● IDO_15 - This delivers a one second pulse to trip the LFR with an input protection fault.
● IDI-3E - LFR Status – (Input protection) reports the status of the LFR (Latch Fault Relay).
Tamper Resistant Input Protection (NXGpro)
The "Tamper Resistant Input Protection" feature :
1. Tests the proper functioning of the input circuit breaker (ICB). The ICB must function
2. Requires the completion of a test to verify that the input circuit breaker is operating correctly
● The test must be performed and successfully passed before the drive will be permitted to
● The test must be run once initially and will rerun automatically any time the system opens
● If this test is not performed and successfully passed, the drive will be inhibited and will notbe
● This test must be performed and successfully passed if the NXGpro DCR rack is replaced.
8.2.12 Input Over-Voltage Fault
Beginning with Version 5.1.0 release, the Input Over-Voltage Fault will create an Input
Protection (IP) fault.

permitted to run.
– To run this test, apply medium voltage and activate parameter "Test TRIP
Response" (ID 7126). This function will measure the ICB response time.
The input breaker will open during the test and removal of medium voltage
within the required time period will be verified. Parameter "Input Breaker
Open Time" (ID 7125) may be used to adjust the maximum allowable
breaker opening time.
