7. VBL Series Starting and Stopping Methods Regenerative braking coasting to a stop or decelerating to minimum speed is recommended for frequent starts and stops Do not use any of these methods for emergency stopping They may not stop a drive that is malfunctioning Removing AC line power both lines is the only acceptable method for emergency stopping For this reason Minarik Drives strongly recommends installing an emergency stop switch on both AC line inputs see Figure 5 on page 11 WARNING Frequent starting and stopping can produce high torque This may cause damage to motors especially gearmotors that are not properly sized for the application Automatic Restart Upon Power Restoration All drives automatically run to set speed when power is applied and the Run Stop switch is opened Line Starting and Stopping Line starting and stopping applying and removing AC line voltage is recommended for infrequent starting and stopping of a drive only When AC line voltage is applied to the drive the motor accelerates to the speed set by the speed adjust potentiometer or analog signal When AC line voltage is removed the motor coasts to a stop Regenerative Brake to Minimum Speed If using a speed adjust potentiometer connect a single pole single throw switch between terminals S1 and S2 Closing the switch will regeneratively brake the motor to minimum speed Opening the switch will allow the motor to run at a

WARNING z a z z Precautions on page i before attempting to install this product f Do not install rewire or remove this control with input power Mounting e Drive components are sensitive to electrostatic discharge Avoid direct contact with the circuit board Hold the drive by the heat sink only Protect the drive from dirt moisture and accidental contact Provide sufficient room for access to the terminals and calibration trim pots Mount the drive away from heat sources Operate the drive within the specified ambient operating temperature range Prevent loose connections by avoiding excessive vibration of the drive Mount the drive with its board in either a horizontal or vertical plane Six 0 19 5 mm wide slots in the chassis accept 8 pan head screws Fasten either the large base or the narrow flange of the chassis to the subplate The chassis does not need to be earth grounded If you choose to ground the chassis use a star washer beneath the head of at least one of the mounting screws to penetrate the anodized surface and to reach bare metal LVBL Series Speed Adjust Potentiometer Be sure that the potentiometer tabs do not make contact with the potentiometer s body Grounding the input will cause damage to the drive If using a remote potentiometer with a chassis drive mount the speed adjust potentiometer through a 0 38 in 10 mm hole with the hardware provided Figure 3
9. WG wire for logic wiring Use 10 12 AWG wire for power line and motor wiring LVBL Series Shielding Guidelines Under no circumstances should power and logic level leads be bundled together Induced voltage can cause unpredictable behavior in any electronic device including motor controls As a general rule Minarik Drives recommends shielding of all conductors If it is not practical to shield power conductors it is recommended to shield all logic level leads If shielding of all logic level leads is not practical the user should twist all logic leads with themselves to minimize induced noise It may be necessary to earth ground the shielded cable If noise is produced by devices other than the drive ground the shield at the drive end If noise is generated by a device on the drive ground the shield at the end away from the drive Do not ground both ends of the shield If the drive continues to pick up noise after grounding the shield it may be necessary to add AC line filtering devices or to mount the drive in a less noisy environment Logic wires from other input devices such as motion controllers and PLL velocity controllers must be separated from power lines in the same manner as the logic I O on this drive Line Fusing The drives should be fused for protection Use a fast acting fuse rated for 50V or higher and 200 of maximum armature current LVBL Series Connections Quick Disconnect Terminal
