[. . . ] RSi Uni-Torque G Series Drive Installation, Operation, and Troubleshooting Manual BENSHAW ADVANCED CONTROLS & DRIVES Publication# 890014-00-03 !The drive contains high voltage that can cause electric shock resulting in personal injury or loss of life. 3. Wait at least 3 minutes after turning off the AC Input power to the drive. If the bus capacitor discharge circuit fails, high voltage can remain in the drive a long time after the AC power is removed. 5. [. . . ] Caution: Be sure not to cause motor overheating by making too large a deviation from the normal V/F pattern. Output volts 100% F17 F15 normal V/F Starting freq. F14 F16 BaseFreq. Analog input mode selection Setting range : 0 ( Voltage input ), 1 ( Current input ) Related functions : F1, F20 ~ F22 Set F1 to <1> 0 : Set the command frequency reference to a 0 to 10V signal on terminal V1. 1 : Set the command frequency reference to a 4 to 20 mA signal on terminal I. freq. 0V 10 V << Voltage input >> 4 mA 20 mA << Current input >> 33 DESCRIPTION OF PARAMETERS Analog input filter Gain, Bias, Direction setting Setting range : 1 ~ 200 % Max. Input Filter Gain : This parameter regulates the response time of the drive to the analog input signal. With a noisy analog signal, the filter gain setting should be higher for better operation. 10V Input voltage time 1% 100% 200% time Setting range : 50 ~ 100 % Input Gain : Input signal multiplier. In order to fine-tune the input signal for a desired output level, this value must be adjusted so that the maximum output frequency is correctly defined. freq. Setting range : 0 ~ 100 % Input Bias : This sets the offset value for the input signal. If this parameter is set to 50%, the target frequency is set to <maximum frequency / 2> for the input signal of 0V (4mA). freq. 50% 0% 0V(4mA) 10V(20mA) 34 DESCRIPTION OF PARAMETERS Setting range : 0 (directly proportional input) 1 (inversely proportional input) 0 : The frequency command is directly proportional to analog input. freq. 0V(4mA) 10V(20mA) 0V(4mA) 10V(20mA) <<Directly proportional input>> <<Inversely proportional input>> High, Low limit frequency Setting range : 0 ~ Max. 0 ~ High limit Freq. This is to limit the output frequency of the drive. In case the set target frequency is not within the range of the highest and lowest limit, the drive will run at the highest or lowest limit frequency. It has a normal acceleration and deceleration rate below the lowest limit. Max. High limit Low limit preset freq. 35 DESCRIPTION OF PARAMETERS Frequency jump, Band Setting range : 0 ~ Max. 0 ~ 30 Hz This function allows the drive to skip a certain frequency range to avoid mechanical stress to the motor or load components resulting from resonant frequencies. As shown in the picture below, if the drive has a preset jump frequency of 10 Hz and a bandwidth of 5 Hz, it is not possible to set the target frequency within the range of 5. 01 14. 9 Hz. If the preset frequency increases, the driving frequency jumps when the preset frequency reaches over 15 Hz after running at 5 Hz. Conversely, if the preset frequency decreases, the driving frequency changes when the preset frequency goes below 5 Hz after running at 15 Hz. This function is to prevent undesirable resonance that can be caused by the vibration of the gear case / motor and the output frequency of the drive. Driving freq. 5Hz 15Hz preset freq. Decreasing preset freq. Increasing preset freq. 36 DESCRIPTION OF PARAMETERS DC brake frequency, voltage, block time, brake time Setting range : 0 ~ 20 Hz Output freq. Brake frequency : DC brake frequency. DC Braking Frequency Output volts t1:n-delay time Setting range : 0 ~ 20 % Brake voltage : DC brake voltage output. t2:brake time DC Braking Voltage t1 t2 Setting range : 0 ~ 5 sec On-delay time : A time delay before generating the DC brake voltage. Setting range : 0 ~ 20 sec Related functions : F13 Brake time : Amount of time the DC brake is active. In order to enable the DC brake, F13 must be set to <1>. Caution: There is a possibility of an over-current trip if the block time of the DC brake is set to 0 sec. This is because the motor magnetic field has not had time to decay to zero before the DC voltage is output to the motor. 37 DESCRIPTION OF PARAMETERS Slip compensation, Rated slip, Rated current, No-load current Setting range : 0 ( NO), 1 ( YES ) · Slip Compensation : Enable slip compensation Setting range : 0 ~ 5 Hz Rated slip : This parameter is set on the basis of the rated number of rotations shown on the motor nameplate and the number of poles. [. . . ] Be sure to check the drive completely before powering up. Over-voltage protection The drive output is removed if regenerative energy due to the motor deceleration or generative load makes the DC voltage (DC Link voltage) exceed its limit. Current limit protection The drive output is removed if the current exceeds 180% of the its rated current during the time set at F43. (refer to F43). Heat-Sink over-heat The drive output is removed when an overheating condition occurs on the drive heatsink. This condition is detected by the temperature element which is attached to the heatsink. ETH Drive output is removed when there is any over-current greater than the rated motor current for a specified period of time (F44 - F46). Overload capacity: 150% / 1 min. External fault signal External Trip terminal is set. [. . . ]
