- Analogue Torque (Direct) Mode.
Same function as Analogue Torque mode but the update frequency is much higher
(7812Hz). Please note that the top speed and acceleration are NOT controlled in this
mode. Use Analogue Torque Mode if this limitation is required.
- Analogue Gear Mode.
This mode is somewhat similar to Gear mode or Analogue Velocity/Gear mode. The posi-
tion of the motor is controlled by the multifunction I/O, which is configured as input. Ei-
ther a pulse and direction signal can be applied or a quadrature A and B signal from, for
example, an incremental encoder.
The gear ratio specified will determine the basic gear ratio between the applied pulses
and the motor movement. The special feature in this mode is that the basic gear ratio can
be changed +/-5% depending on the voltage applied to the analogue input.
+10V will adjust the gear ratio +5% higher and -10V will lower the gear ratio 5%.
A typical application is feeding mechanisms that require "on-the-fly" adjustment.
- Coil Mode.
Similar to gear mode but the position range can be limited in such a manner that the mo-
tor changes direction every time the upper limit is reached and also if the lower limit is
reached. Both limits can be adjusted. The mode is intended to be used for controlling a
wire/cable guider on a winding machine. The guide will follow the position of the coil
driven by a "main motor" and using this mode it is possible to feed the wire in a very pre-
cise position regardless of the speed at which the "main motor" is running.
- Analogue bi position mode
The motor will move a certain distance or go to one of 2 positions depending on the volt-
age at the analogue input. The voltage at the analogue input will be seen as a digital signal,
meaning either logic low or logic high.
The distance or positions can be set up in 2 internal registers and saved permanently
in the motor.
- Analogue to position
The position of the motor will change proportionally with the voltage at the analogue in-
put, between the zero position and a predefined position.
A typical application could be controlling a valve position using a voltage or a current con-
trol signal.
