770V for high-voltage drives), the regenerative resistor will be disabled.
Please use regenerative resistor protection with caution.
If the motor increases the bus voltage and the protection mechanism is activated, it may
lead to overvoltage condition.
4.11.4 Regenerative resistor parameters
The regenerative resistor capacity is defined by several parameters.
To activate the regenerative resistor protection function in CDHD2S, parameter REGENRES
and/or parameter REGENPOW must be set to a value other than -1, and this is the default value.
Regenerative resistor resistance, in ohms.
Regenerative resistor power , in watts.
Maximum time that regenerative resistor can be continuously activated
(turned on), in milliseconds.
Maximum power of regenerative resistor, in watts.
If the system does not have a regenerative resistor, set REGENRES=-1 and REGENPOW=-1
If the system has a regenerative resistor, the “-1” value of REGENRES or REGENPOW
will disable the regenerative resistor overload protection algorithm.
4.12 Firmware Update
4.12.1 Firmware update preparation
IMPORTANT: Before updating firmware, make sure to do the following:
⚫ Please refer to the release notes and any other documentation provided with the new firmware.
⚫ Since the parameter settings may be lost during the update, please back up the parameters of each
drive in the system and keep these files safe. When the update is completed, the parameters can
be reloaded/restored.
To back up parameters, go to the ServoStudio2 Backup and Restore screen and press the Save
to Backup button.
