6SE7016-1TA61 | Siemens SIMOVERT Masterdrives VC Compact Inverter — DC 510–650V / 2.2kW / 6.1A / 3AC 0–480V / 0–500Hz / IP20

DC-AC Inverter — A Distinct Drive Architecture

The 6SE7016-1TA61 is a DC-AC frequency inverter — it takes a DC bus input (510–650V DC) and converts it to variable frequency, variable voltage 3-phase AC output. This is fundamentally different from the AC-AC drives (MICROMASTER, FR-D740, FC301) described elsewhere in this session, which take an AC mains supply and produce AC output.

In the SIMOVERT MASTERDRIVES system architecture, DC-AC inverter compact units like 6SE7016-1TA61 connect to a shared DC bus supplied by a separate SIMOVERT MASTERDRIVES Rectifier Unit (RU), Line Module, or Active Infeed unit:

Common DC bus operation: Multiple 6SE7016-1TA61 inverter units (and other drive modules) can share a single common DC bus — each inverter supplies its own motor independently. When one motor is braking, it returns energy to the DC bus which other accelerating motors can immediately use — significantly reducing peak power demand from the mains supply.

Multi-drive applications: Machine tools with multiple independent axes, printing machines, winding/unwinding systems, and coordinated conveyor systems commonly use common DC bus architectures — requiring compact DC-AC inverter units like 6SE7016-1TA61.

Key Specifications

Vector Control (VC) — Precision Motor Control

The "VC" designation in SIMOVERT MASTERDRIVES identifies the Vector Control firmware — the drive's motor control algorithm:

Speed control: Vector Control maintains precise motor speed regardless of load variation by continuously estimating the motor's magnetic flux state and controlling torque and flux independently. This closed-loop speed regulation (operating without an encoder in sensorless mode, or with high precision with an encoder) maintains speed accuracy far superior to V/Hz open-loop control.

Torque control: Vector Control can operate in direct torque mode — controlling motor torque rather than speed. This enables applications like tension control in winding systems, force control in press drives, and coordinated master-slave torque sharing.

Dynamic response: The separated torque and flux control of vector control produces faster torque step response than V/Hz — important for machine tool axis drives, servo-class industrial drives, and applications with rapidly varying load.

Application Scenarios

Common DC bus multi-axis installation: A CNC machine tool or printing machine uses a shared DC bus from one SIMOVERT supply module. Multiple 6SE7016-1TA61 compact inverter units are connected to the shared bus — each driving one machine axis or roller independently, while energy from decelerating axes is shared with accelerating axes.

Compact inverter for 2.2kW axis: A machine tool feed axis requires precise vector-controlled variable speed drive in a compact format. 6SE7016-1TA61 provides full MASTERDRIVES VC vector control capability at 2.2kW in a 200g compact package.

FAQ

Q1: Why does 6SE7016-1TA61 have a DC input instead of an AC input?

The DC-AC inverter architecture separates the rectification (AC-to-DC) from the inversion (DC-to-AC motor drive). In a multi-drive system, one rectifier/supply module provides the shared DC bus; multiple 6SE7016-1TA61 compact inverter units each convert this shared DC bus to the variable-frequency AC their individual motors require. This enables energy sharing between drives, reduces harmonic disturbances compared to individual AC-input drives, and allows a single supply module to be sized for the net peak demand of the multiple drives rather than their individual peaks.

Q2: What supply module is needed to provide the 510–650V DC bus for 6SE7016-1TA61?

The DC bus for 6SE7016-1TA61 is provided by a compatible SIMOVERT MASTERDRIVES supply module — typically a Rectifier Unit (RU), Regenerative Rectifier Unit (AFE), or similar DC source. The supply module is selected based on the total power demand of all compact inverter units sharing the DC bus. The supply module's output voltage must be within the 510–650V DC range specified for 6SE7016-1TA61.

Q3: Can 6SE7016-1TA61 be used with an encoder for closed-loop position control?

The SIMOVERT MASTERDRIVES VC supports encoder feedback when an appropriate encoder evaluation board is installed in the drive system — enabling closed-loop speed control with higher precision and enabling position control (with position controller). The base 6SE7016-1TA61 compact unit requires the appropriate option board to be added for encoder-based closed-loop operation. Without an encoder, the drive operates in sensorless vector control mode.

Q4: What is the rated overload capability of 6SE7016-1TA61?

Two overload ratings are confirmed: VT (Variable Torque) mode at 6.1A — the drive can deliver 136% of this current for 1 minute; CT (Constant Torque) mode at 5.6A — the drive can deliver 150% of this current for 1 minute. Select VT for fan and pump loads with low transient torque demands; select CT for conveyor, hoist, and machine tool loads requiring sustained torque at all speeds.
