5.3.6 Electronic gear
It is necessary to adjust the electric gear ratio to convert from the command pulse sent from the position
unit to the travel amount of the electrical actuator.
For the recommended parameter for each actuator, refer to"LECSB Operation Manual (Simplified Edition)
”,
section 5.3.4.
Please change the value of electronic gear by use of the customer.
(1) Set the parameter: [PA05], [PA06], [PA07] of LECSB driver.
