TLH/TLL (Torque Control Signal H/L)
J
The TLH signal functions when 6CN-10 turns ON.
The TLL signal functions when 6CN-11 turns ON.
The TLH and TLL signals are used to temporarily control the torque of the motor in operation.
D
When the TLH or TLL signal is turned ON, the torque will be controlled and the TLE torque control
D
signal will be output.
The torque control level with the TLH signal input will be set between 5% and 120% of the 30-minute
D
rating in C1-24 (TLEXT), the external control torque limit level constant.
The TLL operation level will be 1/2 of the TLH operation level.
D
The TLL signal will take precedence over the TLH signal if both TLH and TLL signals are turned ON
D
simultaneously.
Torque control level
The TLL control function will be enabled while the emergency stop is operating.
D
When the TLH or TLL signal is not used, turn 6CN-10 and 6CN-11 OFF.
D
INC (Incremental Signal)
J
INC Function Selection: 6CN-11 will be the INC signal if bit 0 of the C1-36 selection signals (SEL1) is
turned OFF and bit 1 is turned ON.
C1−36
Bit
The INC signal functions when 6CN-11 turns ON.
Used for incremental operation under orientation control.
D
The INC signal will be enabled if it is input earlier than or simultaneously with the ORT signal.
D
If the INC signal is input when the system is turned ON or during absolute positioning, an INC signal
D
fault (AL-65 or AL-75) will result.
The INC signal will start incremental operation from the stop position when the ORG signal input turns
D
ON. If positional precision of the system is required, execute absolute positioning first.
SSC (Soft Start Cancel Signal)
J
SSC Function Selection:
C1−36
Bit
The SSC signal functions when 6CN-12 turns ON.
The SSC signal cancels the soft start function (C1-10) so that the speed standard will catch up with
D
the speed reference for inching.
When the SSC signal is turned ON, the motor will be accelerated or decelerated within the shortest
D
period in current-limited acceleration or deceleration regardless of the acceleration or deceleration
time set in the C1-10 constant.
Turn pin 12 OFF when SSC is not being used.
D
120%
ON
TLH or TLL
1 0
6CN-12 will be the SSC signal if bit 03 of the C1-36 selection signals (SEL1)
is turned OFF.
