9.5 History Monitor Function
■Latest backup data
The latest backup data outputs the following data saved in the fixed cycle to the buffer memory.
• Feed current value
• Servo command value
• Encoder single revolution position
• Encoder multiple revolution position
• Time 1 (Year: month) data
• Time 2 (Day: hour) data
• Time 3 (Minute: second) data
• Latest backup data pointer
The latest backup data starts outputting the data after the power on.
After the home position is established in the absolute system, the data becomes valid and outputs the current value.
The following servo amplifier and servo motor are connected artificially during amplifier-less operation. Therefore, the encoder
single revolution position and encoder multiple revolution position made virtually by the command value are output.
■Backup data at the power disconnection
The detail of the latest backup data right before the power disconnection is output to the buffer memory.
The backup data at the power disconnection starts being output after the power on.
The detail of the latest backup data right before the power disconnection used in the absolute system setting is output,
regardless of the setting of the absolute system or incremental system.
If the data has never been used in the absolute system in the incremental system setting, "0" is output in all storage items.
■Backup data at the power on
After the power on, the detail of the data which restored the current value is output to the buffer memory.
The backup data at the power on starts being output after the power on.
If the current value cannot be restored in the absolute system, "0" is set to the feed current value and servo command value.
The warning "Home position return data incorrect" (warning code: 093CH) is set in the error/warning code at current value
restoration.
When the incremental system is set, the detail of the backup data at the power on used in the absolute system setting is
output. If the data has never been used in the absolute system, "0" is output in all storage items.
■Home position return data
The following data saved at home position return completion to the buffer memory.
• Feed current value at home position return completion
• Servo command value at home position return completion
• Encoder single revolution position of absolute position reference point data
• Encoder multiple revolution position of absolute position reference point data
• Time 1 (Year: month) data
• Time 2 (Day: hour) data
• Time 3 (Minute: second) data
The data becomes valid only when the absolute system is set.
If the data has never been used in the absolute system in the incremental system setting, "0" is output in all storage items.
