The torque upper limit in speed control is input through digital
terminals and the value is determined by F2‑10 (digital setting
of torque upper limit in speed control).
1: AI1
The torque upper limit in speed control is input through AI1.
The frequency is calculated based on the current or voltage
signal input through AI1 according to the set AI curve.
2: AI2
The torque upper limit in speed control is input through AI2.
The frequency is calculated based on the current or voltage
signal input through AI2 according to the set AI curve.
3: AI3
The torque upper limit in speed control is input through AI3.
The frequency is calculated based on the current or voltage
signal input through AI3 according to the set AI curve.
4: Pulse reference (DI5)
The torque upper limit in speed control is input through DI5
(pulse frequency). The frequency is calculated based on the
curve of relationship between the pulse frequency and running
frequency.
5: Communication
The main frequency value is set through communication. The
running frequency is input through remote communication.
The AC drive must be equipped with a communication card to
communicate with the host controller. This channel is
applicable to remote control and centralized control of
multiple devices or systems.
6: Min. (AI1, AI2)
The torque upper limit is the minimum input through AI1 and
AI2.
7: Max. (AI1, AI2)
The torque upper limit is the maximum input through AI1 and
AI2.
