- Analogue Velocity (with deadband) Mode.
Same function as Analogue Velocity Mode but a deadband around zero is inserted.
The deadband is +/-600mV. This feature is useful if a potentiometer or similar device
is used to control the speed of the motor, since the motor will be stationary if the
input voltage is almost at zero.
- Analogue Velocity/Gear Mode.
This mode is similar to Gear mode but it is possible to increase or decrease the po-
sition of the motor by adjusting the voltage applied to the ±10V input. A typical ap-
plication is feeding mechanisms that require "on-the-fly" adjustment.
- Velocity/Analogue torque Mode.
The motor torque is fully controlled by a voltage applied at the ±10V analogue input.
This mode is useful if the motor is used for winding applications where a constant
torque is required in the process. Another typical application is as a slave driver in
multi-axis systems with a master position controller for several axes. The update fre-
quency is 521 Hz. Use Analogue Torque (Direct) if a higher bandwidth is required.
- 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 po-
sition of the motor is controlled by the multifunction I/O, which is configured as input.
Either 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 puls-
es 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
motor 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 con-
trolling 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 precise position regardless of the speed at which the "main motor" is run-
ning.
- Analogue bi position mode
The motor will move a certain distance or go to one of 2 positions depending on the
voltage 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
input, between the zero position and a predefined position.
A typical apllication could be controlling a valve position using a voltage or a current
control signal.
