Use this output to notifya control device such as a PLC of abnormal operating conditions.n Switching Between Torque and Speed ControlUse a digital input to switch Torque Control and Speed Control (H1-oo = 71). When switching from Speed Control to TorqueControl, the torque limit becomes the torque reference and the speed reference becomes the speed limit. This change is reversedwhen switching back to Speed Control.If required by the application, set up a delay time using parameter d5-06. The reference values (torque reference/speed limitin Torque Control or speed reference/torque limit in Speed Control) are held during this switch delay time. Change the referencevalues from the controller within this delay time.Note: 1. The switching delay time d5-06 is not applied when the Stop command is entered. Here the operation switches immediately to speedcontrol and the drive decelerates to stop at the torque limit.2. Set d5-01 to 0 when switching between Torque Control and Speed Control. An oPE15 (Torque Control Setting Error) alarm will betriggered if parameter d5-01 is set to 1 while H1-oo is set to 71 at the same time.1.4 d: Reference Settings70 YASKAWA ELECTRIC SIEP YEAHHP 01B YASKAWA AC Drive – A1000 HHP Programming Manual
