    1 - Safety Precautions According to the EEC standards the AGy -L and accessories must be used only after checking that the machine has been produced using those safety devices required by the 89/392/EEC set of rules, as far as the machine industry is concerned.
  • Page 5 If the front plate has to be removed because of ambient temperature higher than 40 degrees, the user has to ensure that no occasional contact with live parts may occur. Do not connect power supply voltage that exceeds the standard specification voltage fluctuation permissible. If excessive voltage is applied to the drive, damage to the internal components will result.

  • Page 6: Introduction

    2 - Introduction AGy -L is a series of dedicated drives used to control lift asynchronous motors ranging from 4.0 to 200 kW. Thanks to the special lift application software, it is best used in case of plant modernization and, in general, in all open loop applications up to 1 m/s and higher in all closed loop applications, by using EXP-ENC-AGy option.

  • Page 25: Default Lift Configuration

    In AGy -L drives, commands are always coming from Lift Control Word. It is possible to issue the Run Fwd or Run Rev commands from keypad, in order to simplify the startup procedure.
  • Page 26 Each command may come from any of the drive digital input terminals (either standard or expanded), or can be a logical combination of terminal inputs, obtained by using the drive internal programmable area It is anyway possible to assign commands different from the default ones: For example, if we want the Enable command to come from the digital input 3 of the drive (terminal 24 on the regulation board), we have to set parameter I.000 Enable src to the value “[4] DI 3”.
  • Page 27 Ramp Sel 1 ... 2 The binary code defined by the status of these signals selects the set of parameters for ramp profile (jerks, acceleration and deceleration). By default, the first ramp selector is commanded by the ShortFloorFl (see chapter 7.3), while the second ramp selector is fixed to FALSE. Therefore, the first ramp set is normally active, and the drive will automatically switch to the second ramp set whenever a short floor is detected (see Fig.7.5).

    deceleration ramp is too slow, as compared to the re-aligning distance, the lift car could stop after the floor level. If acceleration and/or deceleration ramps are too fast, the drive may reach the output current limit. In this case, the drive will automatically clamp the current to a safe value, with a resulting loss of output torque.
