8.3 Description of the DIP switches S3
DIP switch S3/1 Motor protection activated or deactivated
• If the MOVIMOT
®
inverter is mounted close to the motor (with option P2.A or in the
field distributor), the motor protection must be deactivated.
• To ensure motor protection after all, a TH (bimetallic thermostat) must be used.
DIP switch S3/2 Motor rating class smaller
• If it is activated, the DIP switch enables the assignment of MOVIMOT
®
to a motor
with a smaller rating class. The rated power of the unit remains unchanged.
• If a motor with less power is used, the overload capacity of the drive may increase
since the motor considers the MOVIMOT
®
to be one power increment too high. A
larger current may be impressed for a short period of time, which results in higher
torques.
• The purpose of switch S3/2 is the short-term utilization of the motor peak torque. The
current limit of the respective unit is always the same, independent of the switch set-
ting. The motor protection function is adapted in reference to the switch setting.
• In this operating mode with S3/2 = "ON", a pull-out protection of the motor is
not possible.
DIP switch S3/3 Setting the maximum PWM frequency
• With setting DIP SWITCH S3/3 = OFF, MOVIMOT
®
operates with 4 kHz PWM fre-
quency.
• With setting DIP SWITCH S3/3 = ON, MOVIMOT
®
operates with a 16 kHz PWM fre-
quency (low noise) and switches back in steps to lower switching frequencies de-
pending on the heat sink temperature.
DIP switch S3/4 No-load damping function (S3/4 = ON)
Upon activation, the function prevents resonant oscillations in no-load operation.
