Emotron MSF 2.0 Softstarter

JOG commands can be given via analogue/digital input.The analogue/digital input can be configured either for JOGforward or JOG reverse (see description of menu [500] onpage 77 for more information). Slow speed will be active aslong as the signal on the analogue/digital input is active.If serial communication control is chosen (parameter[200]=3) and the JOG commands are enabled in menus[334] and [335], the JOG commands can be given via serialcommunication. (See separate instruction manual for serialcommunications options.)JOG forward enable [334]In this menu the command for JOG in forward direction isenabled. Depending on the control source chosen in menu[200], the JOG forward command may be accepted fromthe control panel, via remote control or serial communication.NOTE: The enable functions are for all control sources.Bypass [340]As the MSF 2.0 is designed for continuous running, a bypasscontactor is not normally needed. However, where thereis high ambient temperature or other special conditions, theuse of a bypass contactor can be advantageous. In this casethe by-pass contactor can be controlled by one of the relays.By default, relay K2 is configured to control a bypass contactor(for full voltage functionality, see description of menus[530]-[532] on page 85 for more information).The use of a bypass contactor can be combined with anystart and stop method without any connection changesbeing necessary. However, to use the motor protection functions,the shaft power monitor and the viewing functions inbypassed state, the current transformers have to be movedoutside the softstarter. For this purpose an optional extensioncable is available, see chapter 12. page 107 (Options)for more information. Figures 49 - 51 below show a connectionexample.If a bypass contactor is used, bypass operation must be enabledin menu [340] for the softstarter to work properly.3 3 4Setting3 4 0SettingDefault:Range:oFFonoF FJOG forward enableoFFoFF, onJOG forward disabledJOG forward enabledDefault:Range:oFFonoF FBypassoFFoFF, onBypass disabledBypass enabled.JOG reverse enable [335]In this menu the command for JOG in reverse direction isenabled.
