Note: parameterization Set the control input functions to: IN1: Motor right PS1 IN2: Motor left PS1 IN3: Slow-speed mode IN4: Trip/reset (factory default) The slow-speed parameters in Parameter Set 1 must be set. Motor right means rotation in line phase direction, motor left means rotation against the line phase direction. Notice The slow-speed function is not suitable for continuous operation. The motor heating can become unreliable in continuous operation at slow speed. Caution - risk of restart: The start command must be reset before a reset command is issued, as an automatic restart is executed when a start command is pending after the reset command is issued. This especially applies to motor protection tripping. K1, K2, K3 = relays for contact multiplication, e.g. for 230 V AC operation: 3RS 1800-1BP00
