Softdrive 300 Series Technical Information
Softdrive 300 is mechanically protected to IP20 with a simple keypad with LCD display in a multi language format and pushbuttons for setting up.
The parameters are adjustable on a two menu format. The first menu is for standard parameters commonly adjusted by the end user with a second menu for parameters not as commonly used.
The LCD keypad is mounted on the module with an option available which provides a blanking plate and screened ribbon cable to allow mounting of a complete keypad on the panel door.
Communications are available on RS422 via a user friendly set up disk for PC’s or alternatively PROFIBUS and/or DeviceNet are available by the addition of a communications card to the standard assemblies.
The definition files for the Softdrive 300 Fieldbus communications drivers are available for download here.

- Ramp Up sets the desired acceleration time for the motor. Adjustable from 0-240 seconds.
- Current Limit holds voltage ramp once a preset level is reached. Adjustable 100-500% FLC.
- Pedestal Down sets level of voltage before Ramp Down commences. Adjustable 100-20% of line volts
- Ramp Down sets acceleration rate for motor. Adjustable from 0.5-240 seconds.
- Zero sense sets switch off point for deceleration Adjustable from 0-70% of line voltage.

Protection
The Softdrive 300 has a comprehensive protection package that means little additional equipment is required. The Softdrive 300 as standard includes:-
- 1²t electronic overload with selectable curves (includes extended ramp curves)
- Second overload option for dual motor/two speed motor circuits.
- Instantaneous overcurrent relay
- Adjustable undercurrent relay
- Under voltage protection
- Phase imbalance protection
- Overtemperature production
- Thermistor protection
- Earth fault protection *
* Earth fault protection requires a separate core balance CT available from Softstart Direct with 50, 80 and 120mm internal diameter.
All protection remains in circuit during, running and by-pass mode through internal link bars. Therefore Softstart Direct have 6 output terminals for the motor and one set for the bypass contactor.
