Frequently Asked Questions (FAQ)
Q1: What is the Siemens 6SE6420-2UC13-7AA1?
It is a MICROMASTER 420 variable frequency drive rated at 0.37 kW with a 1/3 AC 200–240 V input. It is the unfiltered variant supplied without an operator panel.
Q2: What is the power rating of this drive?
The drive is rated at 0.37 kW for both constant torque and variable torque applications, with a rated output current of 2.3 A.
Q3: Does this drive include an EMC filter?
No. This is the unfiltered variant (indicated by the “A” in the part number suffix). For an integrated filter, the 6SE6420-2UC13-7BA1 variant should be selected.
Q4: Does this drive include an operator panel?
No. The drive is supplied without an AOP or BOP operator panel. If local control is required, the BOP (6SE6400-0BP00-0AA0) or AOP (6SE6400-0AP00-0AB0) must be ordered separately.
Q5: What is the input voltage and phase configuration?
The drive accepts 1/3 AC 200–240 V input, meaning it can operate on either single-phase or three-phase supply within this voltage range.
Q6: What is the maximum output frequency?
The maximum output frequency is 650 Hz.
Q7: Does this drive support communication protocols?
The drive has an integrated RS485 interface and supports PROFIBUS (with an optional module), CANopen, and DeviceNet.
Q8: What is the protection class?
The drive is rated IP20 for installation in protected cabinets.
Q9: What is the operating temperature range?
The operating range is -10 to +50 °C (14 to 122 °F).
Q10: Is this product still in production?
No. The MICROMASTER 420 series has been discontinued by Siemens. This unit is available as remaining stock or refurbished for maintaining existing installations.
Q11: What should I verify before ordering?
Always verify the exact part number (6SE6420-2UC13-7AA1 for unfiltered version), confirm your motor power requirement (0.37 kW), ensure your supply voltage matches (200–240 V AC, 1/3 phase), and determine whether you need an operator panel or integrated EMC filter for your installation.
