Operation as voltage controller

The integrated Speed Controller can be configured as a voltage controller. The motor volt-
age is output in proportion to the voltage at the speed set value input U
tion remains active.
A supervisory controller can be used in Voltage controller mode. The Speed Controller then
acts as a power amplifier for commutation.

Set-point specification

The following setting options for set value specification are possible:

Fixed speed specification


 Analogue set value specification
 PWM set value specification
5.2.1 Fixed speed specification
In fixed speed mode, the motor is operated at a certain speed. In this case, the set speed to
be set is fixed using a parameter (see chap. 5.4, p. 32).
The following settings for the speed set value input U
 Quick-stop input (low level)
 Motor stop with U
Motor stop with open connection

 Motor start with U
 Quick-stop input inverted (high level)
Motor start with U

 Motor runs with open connection
Motor stop with U

No function

 Motor always runs

Explanation
The following set value specifications can be set (see chap. 5.2, p. 28):
 Fixed speed mode
 Speed set value specification via analogue signal
 Speed set value specification via PWM signal at speed set value input
Frequency output: The number of lines per revolution which is output at the
frequency output can be set. Possible values are 2 and 6 lines per revolution.
