Overview of Alarms
SIMODRIVE alarms
310706 Axis %1 drive %2 maximum working speed invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: Because of the high maximum motor speed in the drive MD 5401: DRIVE_MAX_SPEED and the
speed controller cycle in MD 5001: SPEEDCTRL_CYCLE_TIME sufficiently high speeds can occur to
cause a format overflow.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Reduce the maximum working speed in MD 5401: DRIVE_MAX_SPEED or set a smaller speed
controller cycle in MD 5001: SPEEDCTRL_CYCLE_TIME.
Program Switch control OFF - ON.
Continuation:
310707 Axis %1 drive %2 STS configuration of axes differ
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The configuration of the control block MD 5003: STS_CONFIG (STS configuration) must be identical
for both axes on 2-axis modules.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check drive MD 5003: STS_CONFIG (STS configuration) and set the bits for the two axes of the
module so that they are the same. (Do not change the default setting - this corresponds to the optimum
configuration).
Program Switch control OFF - ON.
Continuation:
310708 Axis %1 drive %2 number of encoder marks of measuring system invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The number of encoder marks of the motor measuring system in the drive MD 5005:
ENC_RESOL_MOTOR (number of encoder marks of the motor measuring system) is zero or greater
than the maximum input limit.
Reaction: NC not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Match the number of encoder marks of the motor measuring system in drive MD 5005:
ENC_RESOL_MOTOR (number of encoder marks of the motor measuring system) to the encoder in
use. (Default setting for motor measuring system: (Default setting for motor measuring system: 2048
incr./rev.).
Program Switch control OFF - ON.
