5.2
Open loop operation (PWM mode)
Driver basic operation mode is an open loop mode. At this mode setting value is transmitted directly as
Pulse Width Modulation signal duty value which control motor. Setting value is calculated in relation
1/10. It means that setting value equal to 1 corresponds to 0.1% PWM signal duty. Setting sign
determines motor rotation direction, regulation range is from -96% up to 96% input voltage. Exemplary
setting values:
Maximal PWM signal duty can be lower when motor voltage limit is active.

Drive after taking command will be move with
previously set duty. This function is useful while
control using inputs setting (R1-R10) or Jog command

Furthermore at open loop mode current limit is active. If motor current will exceed rated current set at
application settings driver will limit it to safe value. Drive can signalize overloads which is defined at error
handling window.
