Definitions: The SSI transmission must be completed within an NC clock cycle. This is not possible
with its current parameterization.
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Either increase the clock cycle length of the NC or increase the SSI transmission rate
(MD_1030 $MD_ACTUAL_VALUE_CONFIG_DIRECT.Bits 14 and 15).
The following transmission rates are possible: 100 kHz, 500 kHz, 1 MHz and 2 MHz. Cau-
tion: It might be possible that the length of the encoder cable does not allow an increase
in frequency!
Program Con- Switch control OFF - ON.
tinuation:
301718
Axis %1 drive %2 combination of motor/power section invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The motor cannot be operated with the power section selected.
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Check selection of power section.
• Check motor selection.
• Use valid power section.
Program Con- Switch control OFF - ON.
tinuation:
301719
Axis %1 drive %2 power section data incomplete
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The data for the power section are incomplete:
• Operation of a power section with an FDD motor requires: MD_1178
$MD_INVERTER_DERATING_SYN (derating factor at 8kHz)
• Operation of a power section with an MSD motor requires: MD_1179
$MD_INVERTER_DERATING_ASYN (derating factor at 8kHz)
• Operation of a power section with a PE MSD motor requires: MD_1179
$MD_INVERTER_DERATING_ASYN (derating factor at 8kHz)
• MD_1175 $MD_INVERTER_THERM_CURR_ASYN (limit current power section for PE
MSD)
• MD_1177 $MD_INVERTER_RATED_CURR_ASYN (limit current power section for PE
MSD).
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
