Rev. 060211 OPERATING MODES Start: When either FWD or REV Control signal is applied, and after Control Signal Validation Delay, DC power supply on terminals 1/- and 2/+ is directly connected to Load at terminals 3/L1 and 4/L2 with a polarity according to the control signal. The start option can be combined with Stop and/or Dynamic Brake options. the Load will remain continuously de-energized waiting for a new FWD or REV Control signal. Soft Stop/Ramp Down time is tied to Soft Start/Ramp Up time selected by SA, SB and SC suffixes and can be combined with Soft Start/Ramp Up only. Stop: Load is disconnected from DC power supply. All FET switches (S1, S2, S3 & S4) inside the DP Series SSC are turned off. This simple Stop option is available only in combination with the simple Start option (suffix Blank). Dynamic Brake: It could be used as a modified Stop where the FET switches inside the DP Series SSC are arranged in such a way that they provide a path for the Load Current to keep flowing after the DC power supply has been disconnected. This mode allows for energy stored in some type of loads to be discharged. i.e. back EMF on DC motors. Timing for Dynamic Brake is selected by suffixes B2, B5, B8 and B where the latest will keep the braking or discharging path enabled for as long as FWD and REV Control signals are removed. Soft Start/Ramp Up: It is a modified Start where the DC power supply is connected to the load using a 200 Hz pulse width modulation with a duty cycle going from 10% to 100%. Soft Start/Ramp Up time is defined by SA, SB and SC suffixes. After Soft Start/Ramp Up time is elapsed, the Load will remain continuously energized for as long as FWD or REV Control signal is applied. This option can be combined with Soft Stop/Ramp Down and Dynamic Braking modes, but not with simple Stop. Soft Stop/Ramp Down: It is a modified Stop where the DC power supply is disconnected from the Load using a 200 Hz pulse width modulation with a duty cycle going from 100% to 0%. After Soft Stop/Ramp Down time is elapsed, Interlock: It will shut down all FET switches inside the DP Series SSC within 0.2 sec after both control signals FWD and REV are applied at the same time. An Interlock condition will trigger a modified Stop such as Soft Stop/Ramp Down or Dynamic Brake whenever an option has been selected.
