(1) This is used with the 6W~40W induction speed control motor and the 6W~40W reversible speed control motor. (2) Number of revolutions may be controller and designated with the speed setter on the front of the case. (3) Instantaneous braking is possible with an electric brake. (4) The small 11 Pin plug-in method was used. (5) It has slow run and slow stop function, so operating and braking are not working rapidly, instead, slowly. (6) It is simple to control because the slow run and slow stop functions have time setting functions. (7) Our company's socket (SS) type standard speed controller may not be used for parallel operations. When parallel operation is necessary, the socket (SS) type high-output speed controller should be used.
(1) It is used in the 6W~90W induction speed control motor, the 6W~40W reversible speed control motor and the 6W~40W electro-magnetic brake speed control motor. (2) An external controller can control the number of rotation of the motor. (3) Intantaneous braking is possible with an electric brake. (4) Installation and operation is simple because of a compact plug-in 11 pin type. (5) It has slow run and slow stop functions, so operating and braking are not working rapidly instead, slowly. (6) It is simple to control because the slow run and slow stop functions have time setting functions. (7) Parallel operation is possible. Parallel operation allows multiple motor control packs to be operated at the same speed with one speed setter.
(1) Use of slow run and slow stop The SRSS function of the socket SS type speed controller allows slow acceleration with slow run and gradual deceleration with slow stop function. This function relivevs impact when accelerating and decelerating and should be used when smooth acceleration and deceleration are desired. Slow run and slow stop functions have time setting functions. The variable resistor in the control pack allows time to be set within 0.5 seconds~15 seconds/1200[rpm]. Slow stop braking in a shorter time than the natural braking of the motor is impossible. When slow operation is not necessary, turn the volume switch inside all the way to the left (counter-clockwise).
(2) Characteristics of instantaneous braking The control pack has an electric brake which allows instantaneous braking of the motor within 0.1 seconds. Brake current operates for about 0.5 seconds and then automatically discharges. Because there is no holding torque to hold the motor, after it stops, it is possible to control the location. When holding torque is necessary to stop an object that is moving up and down, use our companys electro-magnetic brake control motor.
∝Note In the control pack, after instantaneous braking, it takes about 0.5 seconds before the motor starts rotating after the brake switch is turned to operate. In the control pack, if instantaneous braking is applied with the variable resistor at 0з or with the run/stop switch at stop and then turned to run again, the motor might rotates once, so do not operate it in this manner. If the run/stop switch is repeatedly switched from the AC power source within 0.5 seconds, the motor might momentarily rotates, so do not run/stop with the AC power source.
(3) Temperature rise of the motor The AC speed control motor gets higher input power as the load increases so the rise in temperature is greater with a larger load. The curve with the temperature rise of the motor, the threshold torque and the number of rotations are called the safe operation line. Use the motor at the torque and number of revolutions below the curve. Safe operation line may be used at above the curve in the following cases.
> When radiation is high. > When a cooling fan is used. > When the ambient temperature is low.
≮ Use at surface temperature of the motor case below 90∩
1) Cautions in installation Use in temperature range with -10∩~+50∩ and less than 85% humidity. Avoid places with direct sunlight, moisture and oiliness. When used in such places, use a cover. Avoid places with vibration, shock, dust, inflammable and corrosive gas.
2) Cautions in wiring Use sockets for connection and do not solder on the PIN of the main body. When connecting the socket, check the terminal number. When inserting the control pack in the socket, turn the power off, check the PIN number and then insert. High-output motors, solenoid, high frequency power and electric welding machines could cause malfunctions of the control pack. Use a separate circuit and wire the above equipment circuits separately.
Note) 1. The specification of L1~L2 should be such that it is not magnetically saturated by the motor current. 2. The condenser and the motor should be grounded in the same place. 3. Use short wiring and ground with thick wires.
Install a noise filter to prevent malfunctions. Install the motor and the control pack as closely as possible. When noise filters are necessary for independent parts, use a circuit as shown in the picture.
3) Cautions in operation Use at a motor surface temperature below 90∩ in rated load. Frequent instantaneous braking and repetition of operating raises the temperature of the motor. When stopping for a long time, turn the power off. Do not operate or stop the motor with the AC power source. The surge voltage from the switch could destroy the product.
1) Check To raise efficiency and use the control pack longer, checking is aquired for followings. ㄧ Is operation being carried out smoothly? ㄨ Is there a strange noise when operating? ㄩ Is abnormal heat being generated? 2) Cause of malfunctions and management methods
