Ramp down detection

Function block diagram

General description

The Ramp down detection function block checks whether a connected drive has been
stopped, meaning that for a configurable time no pulses have been detected from the
encoder system (e.g. from a HTL encoder or proximity switches). Depending on the
result of this check e.g. a safety door lock can be unlatched.

The ramp down detection is started by a falling edge of the

Drive released

input

signal. A stop of the drive is detected when no signal change (falling or rising edge) at
any

Incremental

input has occurred for at least the configured

Min. time between

signal changes

. In this case the

Ramp down ended

output will change to High. If the

Drive released

input signal becomes High, this will immediately set the

Ramp down

ended

output to Low and will also cancel a currently running ramp down detection.

During the running state (i.e. while the

Drive released

input is High) and during the

stop detected state (

Ramp down ended

output is High) the

Incremental

inputs are

not monitored for signal changes (see Figure 163).

The function block allows an optional plausibility check of the

Incremental

inputs to

detect cable interruptions, provided that the encoder provides appropriate signals, e.g.
complementary outputs or proximity switches and a tooth-wheel with 270° tooth width
and 180° phase shift. If the plausibility check is enabled, at least one signal within a
signal pair must be High at any time. The

Plausibility error incremental

output is set

to High, if this condition is not fulfilled for two consecutive logic cycles. This means that
both inputs of a pair may be Low for the duration of the logic execution time without
causing an error (see also Figure 164).

The

Plausibility error incremental

output is reset to Low if at least one signal within

a signal pair is High and the

Drive released

input is Low.

The

Fault present

output is set to High if any

Plausibility error incremental

output is

High. The

Fault present

output is set to Low, if all error outputs are Low.
