3.6.6 Stepper motor emulation

This mode emulates the operation of a stepper motor: each pulse received on the frequency input

(terminal board X6 channel A=frequency, channel B=direction) is multiplied by Pr51 and the result is
added to the reference position. The frequency input must be programmed as a direction/sign signal
by setting b42.5=0. Just as in all other operating modes it is possible to enable feed forward, limit the
action of the proportional part, obtain servo-error indication and select the most suitable type of
reset. Note that the frequency count occurs on the negative front of the signal and changes of the
direction signal must be made at least 1

µ

S before the negative frequency front. Unlike stepper

motors, in this case there is no risk of step loss. Refer to

Frequency input connection

chapter for

the connection diagrams.

PARAMETERS FOR OPERATING MODE 11

Pr50

Maximum speed

. Unit=rpm, default=3000, range=0..9000. This parameter makes it

possible to limit maximum motor speed.

Pr51

Reference multiplication factor

. Default=1, range=-0..+4096. This parameter allows

you to set the required multiplication ratio for input reference frequency.

Pr54

Reserved.

Pr56

Servo-error window

. Unit=steps, default=100. If the absolute position error is greater

than the value in Pr56, b70.5 is set to 1. If utilised, b70.5 must be reset by the user, e.g. by
the PLC program, following servo-errors.

Pr57

Position control loop proportional gain

. Default=100, range 0..32000.

Pr60:61 Position control loop reference

. Unit=steps.

Pr62:63 Motor position

. Unit=steps, 4096 steps per revolution.

Pr64:65

Reserved.

b70.5

Servo-error

. b70.5 is set to 1 if the absolute position error is greater than the value in

Pr56. If utilised, b70.5 must be reset by the user, e.g. by the PLC program, following
servo-errors.

b70.6

Feed-forward enable

. Default=0. If set to 1 feed-forward is enabled on the position

controller.

b70.8

Axis lock/release

. With this bit you can lock (=1) or release (=0) the axis from the input

encoder reference.

b70.9

Reserved.

b70.10 Reset type 1

. This command resets motor and reference position.

b70.11 Reset type 2

. Sets motor and reference position equal to the absolute shaft position.

b70.12 Reset type 3.

Sets the reference equal to the motor position.
