4.2
Regenerative option
【
Pr. PA02
】
Set this parameter when the regenerative power generated is large and the driver's built-in regenerative
resistor does not have sufficient regenerative capability.
For the regenerative option to be used, refer to the "Speed – Workload Graph / Required Conditions for
Regeneration Option" in the catalog for each actuator.
For details on how to connect the regenerative options, refer to "LECSN-T Operation Manual,
Section 11.2
”.
4.3 Absolute position detection system
【
Pr. PA03
】
Set this parameter to enable the absolute position detection system.
For details, refer to "LECSN-T Operation Manual, Chapter 12”.
4.4 Function selection A-1
【
Pr. PA04
】
When the forced stop inputs EM2 and EM1 are not wired, they can be enabled forcibly.
To turn on the forced stop input automatically, change Pr. PA04 from the initial value "2000h" to "2100h".
For details, please refer to "LECSN-T Operation Manual, Section 5.2.1”.
However, when enabling the forced stop input, be sure to provide an emergency stop function on the host
side.
4.5 Electric gear
【
Pr. PA06, Pr. PA07
】
The electronic gear must be set to convert pulses from the positioning unit (PLC) into the actuator's travel.
Basically, enter the "Recommended Parameter Values for Each Actuator" in "LECSN-T User's Manual,
Appendix 9”.
The electronic gear can be changed to suit your company's usage.
For details, refer to "LECSN-T Operation Manual, Section 5.4.”

POINT
● This parameter becomes effective when the power is turned off and then turned on again after setting.
Select a regenerative option.
00: Regenerative option is not used.
For drivers of LECSN-T5, do not use a regenerative resistor.
For drivers of LECSN-T5/T7/T8 and LECSN2-T9,
use a built-in regenerative resistor.
02: LEC-MR-RB-032
03: LEC-MR-RB-12
Set this digit when using the absolute position detection system.
0: Disabled (incremental system)
1: Enabled (absolute position detection system)
