PWM period
This function is for terminal HDI only, accuracy of signal will be reduced in both
lowest and highest allowed period ,
please avoid using it on occasions requiring high-accuracy. To use high-speed pulse on terminal HDI as target
frequency, please refer to 5.3.8
Terminal HDI signal selection and processing.
Set value : 54
Revs counting signal
This function is used to calculate the number of rotations when roll diameter is calculated by thickness calculation
method in tension control mode.
Set value : 55 Speed/Torque control switch
When switch from speed control to torque control, torque limit becomes torque command, speed command
becomes speed limit. When switch back from torque control to speed control, torque command becomes torque
limit, speed limit becomes speed command. When switch between speed control and torque control, please set
closed loop vector control (00-21(P.300) = 4, 5) and speed control (00-20(P.400) = 0). If 00-20(P.400) = 1 and
digital input terminal = 55 are set at the same time, the switching function is invalid and only torque control will be
performed.
Set value : 63 Position/Speed control switch
When switch between speed control and position control, please set closed loop vector control (00-21(P.300) = 4)
and position control (00-20(P.400)=2). If 00-20(P.400)=0,1 and digital input terminal =63
are set at the same time,
position control won’t be on and will only perform speed control or torque control.

Set value :58
Analog terminal 2-5 high priority
When this terminal is ON, frequency command source priority will force to 2-5. (If the frequency commands are
given to 4-5, 2-5 and 3-5 at the same time, the priority is 2-5＞4-5＞3-5).
Set value :59 Analog terminal 3-5 high priority
When this terminal is ON, frequency command source priority will force to 3-5. (If the frequency commands are
given to 4-5, 2-5 and 3-5 at the same time, the priority is 3-5＞2-5＞4-5).
Set value :60
Built-in PLC start/stop
When this terminal is ON, built-in PLC starts; when OFF, PLC stops.
Set value :61
SHOM (Homing enable)
Homing mode will be triggered by upper edge when input signal to this terminal.
