Description of functions
28
The following settings can be made by the user:
5.1.2
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
nsoll
. Current limita-
tion remains active.
A supervisory controller can be used in Voltage controller mode. The Speed Controller then
acts as a power amplifier for commutation.
5.2
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
nsoll
are possible:
Quick-stop input (low level)
Motor stop with U
nsoll
< 0.15 V
Motor stop with open connection
Motor start with U
nsoll
> 0.3 V (0.5 V with BL motors in sensorless operation)
Quick-stop input inverted (high level)
Motor start with U
nsoll
< 2 V
Motor runs with open connection
Motor stop with U
nsoll
> 2.4 V
No function
Motor always runs
Designation
Explanation
Set value specification
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
Digital output
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.
