 Descriptions of Parameters

SA-01 Load Share Function select
Sets Load Share for the drive to master or slave. Set this parameter to 0 to disable Load
Share.
No. Name Setting Range Default Setting
SA-01 Load Share Function select 0 to 2 0
0: Disabled
1: Master enabled (sets Load Share for the drive to master).
2: Slave enabled (sets Load Share for the drive to slave).
 SA-02 Torque Reference Source select
Selects how to imput the torque reference for the slave.
No. Name Setting Range Default Setting
SA-02 Torque Reference Source select 0, 1 0
0: Control circuit terminal (analog input)
The slave receives the torque reference signal from the master using analog terminal A1, A2,
or A3.
1: MEMOBUS communications
The slave receives the torque reference signal from the master using MEMOBUS/Modbus
communications.

SA-03 Torque Signal Select
Selects the type of torque signal that the slave receives from the master.
No. Name Setting Range Default Setting
SA-03 Torque Signal Select 0, 1 0
Note: The SA-03 parameter on the master and slave must be set to the same value.
0: Internal torque reference
Uses U1-09 as the torque signal between the master and slave.
1: Motor secondary current
Uses U6-01 as the torque signal between the master and slave.

SA-04 Torque Limit Select
Enables and disables the Torque Limit function for the slave. Enable this function to use the
torque signal received from the master as the torque limit of the slave.
No. Name Setting Range Default Setting
SA-04 Torque Limit Select 0, 1 0
0: Disabled
1: Enabled

SA-05 Torque Limit Bias
Sets the offset amount of the torque signal received from the master as a percentage of
motor rated torque. This function can be used when SA-04 is enabled.
No. Name Setting Range Default Setting
SA-05 Torque Limit Bias -100% to 100% 10%

SA-06 Torque Filter Time
Sets the primary delay time of the torque feedback value of the slave. Reduce the setting
value when the response of Load Share is slow. Increase the setting value when oscillation
occurs.
No. Name Setting Range Default Setting
SA-06 Torque Filter Time 0.00 s to 2.00 s 0.10 s
