IL[N] - Input Logic

Purpose:
Defines the logic level and functional behavior of the digital inputs. The drive has
several non-committed digital inputs. Each of these inputs can be programmed to a
specific function and logic level. In addition, the IL[N] function enables the simulation
of a digital input. This option is convenient for testing and debugging user programs.

A digital input serves only one dedicated function, which can be reflected in the
following commands/features:

User program auto routine (#@AUTO_##)
Homing procedure (HM[N], HY[N])
IP command
IB[N] command

Notes:

The response to a digital input is made only according to the definition of IL[N].

For example, if digital input #2 is defined by IL[2] as RLS (Reverse Limit switch),
changes in the connector pin of digital input #1 will not be reflected in IB[1]
commands. IB[1] will read zero continuously. In this case, IB[11] will reflect this
input status.

When a digital input is activated, the relevant bit in IP/IB[N] is set. Refer to the

IP

and

IB[N]

commands for more details.

Inputs 5 and 6 also serve as high-speed home/capture inputs, used

independently by the HM[N] and HY[N] commands. The logic level for the
home inputs is also defined by the IL[N] command.

If inputs 5 or 6 are used as home inputs, the corresponding parameters IF[5] and

IF[6] do not apply. The EF[1] and EF[2] parameters are used instead.

The following table summarizes the functions that may be attached to each digital
input pin. The function details are given in the next table. The prefix “Hard” indicates
that the function applies to the stop manager, not to the motion reference generator.
The term “Soft” indicates that the function applies to the motion reference generator.
The term “Hard and Soft” indicates that the function applies both to the stop manager
and to the position reference generator.
