Aerotech Ndrive Linear Drive Selection

In terms of feedback interface, the main encoder input supports 32 MHz square wave standard or 500 kHz sine wave (with MXH). The auxiliary encoder input is a 32 MHz square wave. Encoder multiplication can reach x65536 through MXH and supports real-time orthogonal output. The absolute encoder supports Renishaw Resolute BiSS, EnDat 2.1, and EnDat 2.2. The rotary converter interface can choose 1 or 2 channels, with a 16 bit resolution and a carrier frequency of 10 kHz, 7.5 kHz, or 5 kHz, corresponding to options such as RDP1-10K, RDP1-7.5K, RDP1-5K, RDP2-10K, RDP2-7.5K, and RDP2-5K.

Differentiation between Ndrive CL and ML

Ndrive CL is positioned as a cost sensitive linear drive, model CL10-40. It supports brushed and brushless motors, 10 A peak, 5 A continuous, ± 40 VDC bus.

Ndrive ML is the smallest linear drive in the series, model ML10. It supports brushed and brushless motors, 10 A peak, 5 A continuous, ± 40 VDC bus. The motor power supply is DC, with a maximum of ± 40 VDC; Control power supply 18-36 VDC. Standard I/O only has one 16 bit differential analog input, while digital I/O requires an expansion board. Extended I/O includes 8 digital inputs, 8 digital outputs, 1 16 bit analog input, and 1 16 bit analog output, and supports auxiliary encoders sin/cos/mkr and PSO outputs. PSO is only single axis. Encoder multiplication options include MXU up to x4096 or MXH up to x65536 with real-time orthogonal output. The main encoder input supports 32 MHz square wave standard or 2 MHz sine wave (MXU or MXH). Automatic braking control is optional, with ESTOP standard 24V optical isolation. Current loop 20 kHz, servo loop 8 kHz, minimum load inductance 0, operating temperature 0-50 ° C, weight approximately 1.0 kg, width 92.1 mm, height 141.0 mm.

Ordering Options and Configuration Analysis

The ordering information for Ndrive HLe typically consists of a base, output current, control options, rotary options, and line voltage options. For example, HLe 20-40-X-ENET RDP1-10K. The base is HLe 10-40-X, 20-40-X, or 10-80-X. Line voltage options: A is 115 VAC, B is 230 VAC, C is 100 VAC, and D is 200/208 VAC. The control options include: - I/O expansion board, - DUALPSO dual axis PSO, - TRIPLEPSO three-axis PSO, - PSOPTO2, - PSOPTO3, - PSOPTO4, - PSOAH, - MXH encoder multiplier, - ENET Ethernet. The rotary options include RDP1-10K, RDP1-7.5K, RDP1-5K, RDP2-10K, RDP2-7.5K, and RDP2-5K.

The order for Ndrive CL is CL10-40, with control options - I/O and - MXU. The order for Ndrive ML is ML10, with control options - I/O, - MXU, and - MXH. Attention should be paid when selecting: When CL and ML use integrated MXU, PSO is not available. If both encoder multiplication and PSO are required, HLe's MXH should be selected or the function should be reassigned. HLe's MXH supports real-time orthogonal output, suitable for multi axis PSO and encoder cascading. The MXU of CL and ML does not have real-time output, making it suitable for situations where only resolution needs to be increased without the need to output encoder signals.
