Inverters are electronic devices capable of powering an AC electric motor and of imposing speed and torque values. The inverters of the PENTA series manufactured by Elettronica Santerno SpA allow adjusting speed and torque values of three-phase asynchronous and synchronous motors and brushless, permanent-magnet AC motors by way of several control modes.
INSTALLATION GUIDE SINUS PENTA 1.1. Feature List • One product, multiple functions: vector-modulation IFD function for general-purpose applications (V/f pattern); sensorless, vector VTC function for high torque demanding performance (direct torque control); vector FOC function with an encoder for accurate torque requirements and wide speed range; ...
INSTALLATION GUIDE SINUS PENTA 1.2. Special Applications Available for the Sinus Penta Beside basic parameterization, Sinus Penta drives also implement operating modes and optional functional modes named APPLICATIONS, which can be obtained through firmware updating and additional external components. Optional operating modes available for the inverters of the PENTA series are the regenerative drive control application and the synchronous motor control application.
INSTALLATION GUIDE SINUS PENTA 2. SAFETY STATEMENTS This section contains safety statements. The non-observance of these safety instructions may cause serious injury or death and equipment failure.

INSTALLATION GUIDE SINUS PENTA MECHANICAL MOTION – The drive causes mechanical motion. It is the operator's responsibility to ensure that this does not give rise to any dangerous situation. The STO function may be used to prevent mechanical motion under certain operating conditions.
Page 13
INSTALLATION GUIDE SINUS PENTA Before programming and starting the drive, make sure that the connected motor and all the controlled devices can be used for the whole speed range allowed by the converter. The drive may be programmed to control the motor at higher or lower rpm in respect to the speed attained by connecting the motor directly to the power supply line.
INSTALLATION GUIDE SINUS PENTA 2.2. Permanent Magnet Motors This section covers additional safety statements concerning Sinus Penta drives used with permanent magnet motors. The non-observance of the safety instructions below may cause serious injuries or death and equipment failure. Do not operate on the converter when the permanent magnet motor is rotating. Even if the power supply is cut out and the inverter is stopped, the permanent magnet motor, when rotating, powers the DC-link of the converter, and voltage is applied to the power supply links.

INSTALLATION GUIDE SINUS PENTA 3.5.3.2. DIP-switches The inverter control board includes three banks of DIP-switches (SW1, SW2, and SW3) for the following functions: DIP-switch SW1: analog input configuration DIP-switch SW2: analog output configuration DIP-switch SW3: line termination over line RS485 To gain access to DIP-switches SW1 and SW2, remove the front cover of the control terminals by loosening the relevant fastening screws.
INSTALLATION GUIDE SINUS PENTA Sinus Penta S30 to S60P: interface connector RS485 and DIP-switch SW3 are located next to the control terminal board cover. Sinus Penta S65 and S70: to gain access to DIP-switch SW3, remove the cover located on the rear part of the control board.
INSTALLATION GUIDE SINUS PENTA DIP-switch SW3: interface RS485 terminator Switches Functionality SW3-1, Both OFF: RS485 terminator disabled Both ON: RS485 terminator enabled SW3-2 (DEFAULT) DIP-switch factory setting is as follows: ON 1 SW1- All OFF except 2 and 3 SW2 – Odd numbers ON SW3 - OFF Factory setting provides the following operating modes: REF Analog input (voltage input) and two current analog inputs (AIN1, AIN2)
INSTALLATION GUIDE SINUS PENTA 3.5.4. Digital Inputs (Terminals 14..21 and Terminal S) All digital inputs are galvanically isolated in respect to zero volt of the inverter control board. Consider isolated power supply on terminals 23 and 22 or 24V auxiliary supply before activating the inverter digital inputs.
INSTALLATION GUIDE SINUS PENTA 3.5.4.2. ENABLE-A (Terminal 15) and ENABLE-B (Terminal S) The ENABLE-A and ENABLE-B inputs are always to be activated to enable the inverter operation regardless of the control mode. If the ENABLE inputs are disabled, the inverter output voltage is always set to zero, so the motor performs a coast to stop.
INSTALLATION GUIDE SINUS PENTA 3.5.4.4. Connecting the Encoder and Frequency Input (Terminals 19 to 21) Functionality of the programmable digital inputs is given in the Programming Guide. Digital inputs MDI5, MDI6, MDI7 may acquire fast digital signals and be used for the connection of an incremental encoder (push-pull encoder, single-ended encoder) and/or for the acquisition of a frequency input.

Analog inputs may be configured either as voltage inputs or as current inputs. AIN2 input may be used to acquire a PTC thermistor in compliance with DIN44081/DIN44082 for the motor thermal protection.
INSTALLATION GUIDE SINUS PENTA 3.5.5.1. REF Single-ended Reference Input (Terminal 2) Reference input REF (2) is assigned to the inverter speed reference (factory setting) and is a single-ended input related to terminal CMA (1). The figure below shows wiring to a unipolar potentiometer, a bipolar potentiometer and a sensor with 4÷20mA current output.
INSTALLATION GUIDE SINUS PENTA 3.5.5.2. Differential Auxiliary Inputs (Terminals 5–8) Auxiliary inputs allow auxiliary voltage and current values for signals exceeding ground signals up to a preset maximum voltage value in common mode. A differential input weakens disturbance due to “ground potentials” occurring when the signal is sent from a source that is located far from the inverter.
INSTALLATION GUIDE SINUS PENTA 3.5.5.3. Motor Thermal Protection Input (PTC, Terminals 7-8) The inverter manages the signal sent from one or more thermistors (up to 6 thermistors) incorporated in the motor windings to obtain a hardware thermal protection of the motor. The thermistor ratings must comply with IEC 34-11-2 (BS4999 Pt.111 - DIN44081/DIN44082) or to thermistors named “Mark A”...

Four self-threaded screws are supplied to fasten the brackets to the mounting plate; four fastening screws are also supplied to fix the shell to the panel.
Never connect and disconnect the keypad when the inverter is on. Temporary CAUTION overload may lock the inverter due to alarm trip. Only use wires supplied by Elettronica Santerno for the keypad wiring. Wires with a different contactor arrangement will cause irreparable damages to the CAUTION inverter and the display/keypad.

In case your computer is provided with a serial port RS232-C or a USB port, a RS232-C/ RS485 converter or a USB/RS485 converter is required. Elettronica Santerno may supply both converters as optional components. Logic “1” (normally called a MARK) means that terminal TX/RX A is positive in respect to terminal TX/RX B (vice versa for logic “0”, normally called a SPACE).

The following specifications are recommended: Type of cable Shielded cable composed of balanced D1/D0 pair + common conductor (“Common”)
INSTALLATION GUIDE SINUS PENTA Four-pair data transfer cables of Category 5 are normally used for serial links. Although their usage is not recommended, cables of Category 5 can be used for short cable paths. Note that the colours of such cables are different from the NOTE colours defined by MODBUS-IDA association.

INSTALLATION GUIDE SINUS PENTA 5.2. Carrier Frequency Setting The continuous current (Inom) generated by the inverter in continuous operation type S1 at 40°C depends on carrier frequency. The higher the carrier frequency, the more the motor is silent; the control performance is enhanced, but this causes a greater heating of the inverter, thus affecting energy saving.
