2 CONTROL MODE
2.1 Control mode [G] [WG]
Controlword/Statusword
By changing [Controlword (Obj. 6040h)], control commands can be given to the servo amplifier. The control status can also be
checked with [Statusword (Obj. 6041h)].
Some bits of [Controlword (Obj. 6040h)] and [Statusword (Obj. 6041h)] vary or are common depending on the control mode.
The bits that vary depending on the control mode are listed in the following tables.

8
HALT
0: Drives the servo motor.
1: Stops the servo motor according to [Halt option code (Obj. 605Dh)].

Description

Target reached
0: Halt (Bit 8) = 0: Target velocity not reached.
0: Halt (Bit 8) = 1: Axis decelerates.
1: Halt (Bit 8) = 0: Target velocity reached.
1: Halt (Bit 8) = 1: Velocity of axis is 0.
Judgment condition of Target velocity reached:
When the time set in [Velocity window time (Obj. 606Eh)] elapses in a state where the difference between the
values in [Velocity actual value (Obj. 606Ch)] and [Target velocity (Obj. 60FFh)] is equal to or below the value set
in [Velocity window (Obj. 606Dh)], the state becomes "Target velocity reached".
12
Speed
0: Speed is not equal 0
1: Speed is equal 0
Judgment condition of Speed is not equal 0:
When the time set in [Velocity threshold time (Obj. 6070h)] elapses in a state where the absolute value of
[Velocity actual value (Obj. 606Ch)] is equal to or above the setting value of [Velocity threshold (Obj. 606Fh)], the
bit becomes "Speed is not equal 0".
13
Max slippage error
0: Maximum slippage not reached
1: Maximum slippage reached (not supported)
Max slippage is the maximum slippage of the asynchronous servo motor.
