Overview of Alarms
SIMODRIVE alarms
301701 Axis %1 drive %2 limit value for safe velocity too large
Parameters: %1 = Axis number
%2 = Drive number
Definitions: Booting has been interrupted. The pulses remain disabled.
Request: In monitoring cycle.
The limit value of the safe velocity exceeds the velocity corresponding to a limit frequency of 200 kHz
(300 kHz for 840D with SW4.2 and higher and for 840C with SW6.1 and higher).
The max. permissible speed that can be monitored is determined as follows:
nmax[rev/min] = (200000[Hz] * 60) / encoder marks value
Monitoring condition:
Modify MD 1331: $MD_SAFE_VELO_LIMIT[n] <= (1 / ue) * nmax
Reaction: Mode group not ready.
Channel not ready.
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 entry in the machine data MD
1331: $MD_SAFE_VELO_LIMIT[n] (safe velocity limit values) correct, if necessary, and perform
POWER ON.
Program Switch control OFF - ON.
Continuation:
301702 Axis %1 drive %2 track inversion incorrect
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: With rotary spindles without EnDat interface operating with enhanced controller modules, the track
inversion (MD_1011.0=1) must not be switched on. Otherwise this error is triggered.
Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM)
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. With rotary spindles without EnDat
interface operating with enhanced controller modules, the track inversion must be performed by
soldering the A and B tracks differently: A <-> B and A* <-> B*
Program Switch control OFF - ON.
Continuation:
301703 Axis %1 drive %2 encoder/motor type are not compatible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: If a linear motor was selected (motor selection menu), but no linear scale was configured (MD
1011.4=0), or if a rotary motor was selected, but a linear scale configured (MD 1011.4=1), then this
error is triggered.
Modify MD 1011: $MD_ACTUAL_VALUE_CONFIG (actual value sensing configuration IM)
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Encoder type must be parameterized
according to the motor type.
Program Switch control OFF - ON.
