HONEYWELL MC-PDIY22 80363972-150 Pulse module

If the drive is stopped and should be restarted, the actual condition of the drive has to be taken into consideration: - if STARTSEL (1717) = 0 (start from zero): a. and the actual speed is below MIN_SPEED_L (2201) the drive accepts the 0 to 1 transition of the RUN command and will accelerate according to the reference without handling the ON/OFF signal b. and the actual speed is above MIN_SPEED_L (2201) the 0 to 1 transition is ignored as long as the speed is above this level; if this cannot be accepted because of any reason (e.g. stop by coasting) both inputs must have logic 0 level; afterwards, ON/OFF and RUN should be set to 1 (edge sensitive); the drive will force the motor to zero speed by the torque limit at first and afterwards, the drive will accelerate according to the reference; this behaviour is independant from the selected stop mode remark: if EMF is selected as a speed feedback signal, it may happen, that the drive reacts according to a, because the MIN_SPEED_L is too smal

if STARTSEL (1717) = 1 (flying start): 

the RUN command is no longer edge sensitive; the drive will accelerate according to the reference, when the RUN command is set to 1, independant, if the actual speed was zero or different to zero before; if the drive was stopped by the ON/OFF command (the RUN command was kept to logic 1 level), it will react when ON/OFF changes from 0 to 1 in the same way, as if the RUN command would have been used - Coast Stop When [COAST STOP] (905) input is set to logical state 1, regulators are blocked and contactors remain closed. The drive is allowed to decelerate freely towards zero speed. As long as the drive stops in this way, the stop functions available with the RUN command are disabled and vice versa. This stop mode can be interrupted by Emergency Stop, Stop because of panel or field bus link problems. - Emergency Stop If [EME STOP] (906) signal is set from 1 to 0, the emergency stop function is activated.

Functional Software description

 20 DCS 500 Software Description - Stop because of problems with the panel link (communication between drive and control panel CDP 312) if the serial link between the drive and the control panel is interrupted by any reason (panel removed from the drive, cable broken, etc) the reaction of the drive can be specified by paramter PANEL_DISC_MODE (918): 0 = stop by ramp (DECEL1 (1709) or DECEL2 (1712) ) at RAMP GENERATOR function block 1 = stop by torque limit (TORQ_MAX / TORQ_MIN) 2 = stop by coasting (torque is zero) 3 = stop by dynamic brake 4 = continue remote The drive will come up with a FAULT, which must be reset and which will open all contactors at zero speed (with coasting immediatelly). - Stop because of problems with the field bus serial link (communication between drive and progr. logic controller) if something is wrong with the field bus serial link (between PLC and serial link adapter module
