5 Deactivate the transformation and travel the axis/axes separately

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

21610 [Channel %1: ] Axis %2 encoder %3 frequency exceeded

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = String (encoder number)

Definitions: The maximum permissible frequency of the currently active encoder (axis-specific interface signal

V380x 0001.5 / 1.6 (position measuring system 1/2)) in the axis-specific MD36300

$MA_ENC_FREQ_LIMIT [n] (n ... encoder number, 1 or 2) has been exceeded. The reference of the

actual value to the mechanical slide position may have been lost.

The alarm can be reprogrammed in MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (chan-

nel not ready).

Reaction: Mode group not ready.

Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Channel not ready.

Remedy: Check MD36300 $MA_ENC_FREQ_LIMIT [n] and NC/PLC interface signal V380x 0001.5 / 1.6 (posi-

tion measuring system 1/2).

Program Con-

tinuation:

Clear alarm with the RESET key in all channels of this mode group. Restart part program.

21612 [Channel %1: ] Axis %2: enable reset, cause %3

Parameters: %1 = Channel number

%2 = Axis name, spindle number

%3 = Cause of the alarm

Definitions: Causes of alarm:

0: The cause of the alarm cannot be preceisely determined.

1: The interface signal V380x 0002.1 (Servo enable) is missing

2: The interface signal V380x 4001.7 (Pulse enable) is missing

3: Drive signal V390x 4001.7 (Impulses enabled) is not set

4: Drive signal V390x 4001.5 (Drive ready) is not set

One of the motion-enabling signals (e.g. "Servo enable", "Pulse enable", parking/encoder selection

(only for axes) or drive-specific enables has been reset for the displayed axis. The alarm can be

reported with positioning axes, spindles and for axes from the geometry grouping.

The axes entered in the channel-specific MD array MD20050

$MC_AXCONF_GEOAX_ASSIGN_TAB are regarded as axes belonging to the geometry grouping.

Servo enable must exist for all available geometry axes, regardless of whether or not they are cur-

rently in motion.

Occurs in connection with SAFETY function: If a test stop is performed with linked axes, the alarm is

issued if a motion command from the ELG grouping is pending during the test stop of the slave axis.

Reaction: The NC switches to follow-up mode.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: Please inform the authorized personnel/service department.

Check the interface signals V380x 0002.1 (Servo enable), V380x 4001.7 (Pulse enable), check the

drive signals V390x 4001.7 (Pulses enabled), V390x 4001.5 (Drive ready) for example with the PLC

status display in the DIAGNOSTICS operating area. Check the encoder selection (for axes) as well

as other signals enabling motion (such as SIMODRIVE 611D terminal 663 etc.) according to the drive

type used.

When the terminal enables of the drive have failed, trace back the wiring or hardware function (for

example relay function) or proceed as stated in the relevant drive documentation.

With SAFETY: With active actual-value linkage, output of the error message on the slave axis can be

prevented by increasing MD36060 $MA_STANDSTILL_VELO_TOL (default value is 5 mm).
