50Hz / 60Hz Switch On the MM440 there is a DIP switch that is used to select either 50Hz or 60Hz operation. This is referring to the nominal motor frequency being used. The factory frequency setting (50Hz) can be adapted to NEMA frame motors (60Hz - typically used in North America) by using the DIP2(2) switch behind the I/O board. At power up, the position of the DIP2(2) switch determines the setting of P0100, if P0100 = 0 / 1 then the DIP2(2) switch position has priority over the parameter value and will reset it according to the DIP2(2) position. If P0100 is set to 2 then the DIP2(2) switch is ignored. After power cycling the drive following a change in DIP2(2) position, the parameters for the rated motor frequency (P0310), max. frequency (P1082) and reference frequency (P2000) are automatically pre-set to 50Hz/60Hz defaults (depending on switch position). In addition, the rated motor parameters as well as all of the other parameters which depend on the rated motor parameters are reset. The units of the power parameters are, depending on P0100, either interpreted as kW value or hp value. Commissioning The MICROMASTER comes with a Status Display Panel (SDP) and default parameters settings to cover the following: Motor rating data; voltage, current and frequency are all compatible with the inverter data Linear V/f motor speed, controlled by an analog potentiometer Maximum speed 3000 rpm with 50 Hz (3600 rpm with 60 Hz); controllable using a potentiometer via the inverter’s analogue inputs Ramp-up time / Ramp-down time = 10 s To set up the inverter with your motor, follow the quick commision. Quick Commissioning P0010 1 = Quick Commissioning Start Quick Commissioning P0010 must always be set back to ‘0’ before operating the motor. However if P3900 = 1 is set after commissioning this is done automatically P0100 Operation for Europe / N. America 0 = kW / 50 Hz 1 = hp / 60 Hz 2 = kW / 60 Hz For setting 0 and 1 use DIP Switch 2. For setting 2 use P0100 P0304 Rated Motor Voltage 10 V - 2000 V Nominal motor voltage (V) from rating plate P0305 Rated Motor Current 0 ... 2 * Inom Nominal motor current (A) from rating plate P0307 Rated Motor Power 0 kW - 2000 kW Nominal motor power (kW) from rating plate. If P0100 = 1, values will be in hp P0310 Rated Motor Frequency 12 Hz - 650 Hz Nominal motor frequency (Hz) from rating plate P0311 Rated Motor Speed 0 - 40000 1/min Nominal motor speed (rpm) from rating plate P0700 Selection of Command Source (on / off / reverse) 1 = BOP 2 = Terminal / Digital Inputs (default) P1000 Selection of Frequency Setpoint 1 = BOP 2 = Analogue Setpoint (default) P1080 Sets minimum motor frequency Min. Motor Frequency (0 - 650 Hz) at which the motor will run irrespective of the frequency setpoint. The value set here is valid for both clockwise and anticlockwise rotation P1082 Sets maximum motor frequency Max. Motor Frequency (0 - 650 Hz) at which the motor will run at irrespective of the frequency setpoint. The value set here is valid for both clockwise and anti-clockwise rotation P1120 Ramp-Up Time 0 - 650 s Time taken for the motor to accelerate from standstill up to maximum motor frequency. P1121 Ramp-Down Time 0 - 650 s Time taken for motor to decelerate from maximum motor frequency down to standstill P3900 End Quick Commissioning 0 = End Quick Commissioning without motor calculation or factory reset. 1 = End Quick Commissioning with motor calculation and factory reset (Recommended). 2 = End Quick Commissioning with motor calculation and with I/O reset. 3= End Quick Commissioning with motor calculation but without I/O reset.

as it is described in the parameterlist; p0100 Determines whether power settings (e.g. nominal rating plate power - P0307) are expressed in [kW] = Europa or [hp] = USA.P0100 setting 2 (==> [kW], frequency default 60 [Hz]) is not overwritten by the setting of DIP switch 2 (see diagram p0100 in parameterlist http://support.automation.siemens.com/WW/view/en/23708204 ) |
