Halt [G]; Objects For Setting - Mitsubishi Electric MELSERVO-J5 User Manual

Halt [G]

Halt defined in CiA 402 enables temporary stop of the servo motor.
When 1 is set in Bit 8 (HALT) of [Controlword (Obj. 6040h)], the servo motor decelerates to a stop with the deceleration time
constant of [Profile deceleration (Obj. 6084h)] or [Homing acceleration (Obj. 609Ah)], and then the state remains as
"Operation Enable" (Servo-on), in accordance with the setting of [Halt option code (Obj. 605Dh)]. When Halt Bit is set to 0
during the deceleration stop operation, the servo motor decelerates to a stop and returns to the operable state.
• This function can be used in the profile mode (pp/pv/tq), point table mode (pt), JOG operation mode (jg),
and homing mode (hm). The other control modes can be operated regardless of the Halt Bit status.
• In the profile torque mode (tq), [Torque demand value (Obj. 6074h)] is set to 0 regardless of [Halt option
code (Obj. 605Dh)]. The amount of torque change at this time can be set using [Torque slope (Obj. 6087h)].

Setting value Description
1 The servo motor decelerates to a stop in accordance with [Profile deceleration (Obj. 6084h)] during the profile positioning/velocity mode
(pp/pv) and JOG operation mode (jg), in accordance with the point table deceleration time constant/point table deceleration during the
point table mode (pt), and in accordance with [Homing acceleration (Obj. 609Ah)] during the homing mode (hm), and the servo motor
remains "Operation Enabled".
During the profile torque mode (tq), [Torque demand value (Obj. 6074h)] becomes "0" stopping the servo motor in accordance with the
amount of torque change set in [Torque slope (Obj. 6087h)], and the state remains "Operation Enabled".
2 After deceleration to a stop in accordance with [Quick stop deceleration (Obj. 6085h)], the state remains as "Operation Enabled". (Servo-
(not currently on is maintained.)
supported)
3 After deceleration to a stop by limiting the current, the state remains as "Operation Enabled". (Servo-on is maintained.)
(not supported)
4 After deceleration to a stop by limiting the voltage, the state remains as "Operation Enabled". (Servo-on is maintained.)
