Drive Status Digital Outputs - Lenze SM004S Operating Instructions Manual

3 Installation
NOTE
If TB-13A, TB-13B, and TB-13E are all programmed to select speed references, and two
or three of the terminals are closed to TB-11, the higher terminal has priority and will
override the others. For example, if TB-13A is programmed to select 0-10VDC, and TB-13E
is programmed to select PRESET SPEED #3, closing both terminals to TB-11 will cause
the drive to respond to PRESET SPEED #3, because TB-13E overrides TB-13A.
The exception to this is the MOP function, which requires the use of TB-13B and TB-13E.
This leaves TB-13A to be used for some other function. If TB-13A is programmed for a
speed reference, and TB-13A is closed to TB-11, TB-13A will override the MOP function.

Drive Status Digital Outputs

There is one Form A relay at terminals TB-16 and TB-17. The relay contacts are rated 3 amps at 250 Vac.
Terminal TB-13E can also be configured as a digital output. This output circuit is a current-sourcing
type rated at 12 VDC and 50 mA maximum.
The Form A relay and digital output can be programmed to indicate any of the following: RUN,
FAULT, INVERSE FAULT, FAULT LOCKOUT, AT SPEED, ABOVE PRESET SPEED #3, CURRENT LIMIT, AUTO
SPEED MODE, and REVERSE. Refer to Parameters 06 and 12 in Section 4.4 Description of Parameters.
The diagram below illustrates how TB-13E, when configured as a digital output, can be used to drive
an external relay:
