Additional Modes

Advantages over a conventional stepper motor:

■

The step count per revolution is programmable
and has very high resolution

■

The step width is programmable

■

No torque losses due to cogging

■

The full dynamic capabilities of a brushless
motor

■

The motor is very quiet

■

The motor monitors actual position so that
no steps are “lost”

■

No current flows through the motor after it
has reached the predefined position

■

Very efficient

Input:

Maximum input frequency: 150 kHz
Level: low 0 ... 0.5 V / high 4 ... 30 V
This mode makes true-position speed control
possible and allows the user to set the ratio of
input frequency to rpm with the step width and
step number commands.

The reduction ratio can be calculated with the
help of the following formula:

Revolutions = Pulses · ____

STW

STN

Revolutions

... output revolutions

Pulses

... number of pulses at the

frequency input
(= number of steps)

STW

... step width (Step width factor

... number of steps per pulse at
the frequency input)

STN

... step number (number of steps

per revolution)

STN and STW range: 0 to 65535

Default settings: STN1000 and STW1

Once the motor is configured in Stepper Motor
Mode, the RS-232 is no longer required.

In the event that the direction of rotation input
is not yet programmed, it can be programmed
with the ADR (rotate right) and ADL (rotate left)
commands.

To change the direction of rotation externally,
the Fault Pin can be programmed as the direc-
tion of rotation input with the DIRIN command.

In stepper motor mode the

AC

- and

SP

-values

(see Position Control) are also applicable making
soft acceleration and braking possible.

The command

APL1

applies position limits

(LL-Command) to the sequence. With the
command

APL0

the position limits will be

ignored (Default setting).
