Parameter Instruction Name Value range Defaults Unit Description
P1-19 ZR
Regenerative
resistor resistance
10 ~ 32000 10 Ohm
Set the resistance value of the regenerative
energy absorption resistor
P1-20 ZC
Regenerative
resistor power
rating
1 ~ 32000 40 Watt
Set the power of the regenerative energy
absorption resistor
P1-21 ZT
Regenerative
resistor time
constant
0 ~ 8000 1000 ms
Sets the sustainable absorption time of the
regenerative energy absorption resistor
Note:
Please set the resistance value, power and absorption time of the absorption resistor correctly,
otherwise it will a󰀨ect the use of this function and cause the drive to generate alarms such as
overvoltage and regenerative energy absorption failure.
When connecting an external absorbing resistor, please make sure that the total resistance value
cannot be less than the minimum allowable resistance value of the driver. If multiple resistors are
used in series or in parallel, please calculate the total resistance and total power correctly.
